Granite Grip Outsole

Maximized sole-to-surface contact for increased friction on smooth surfaces. Razor-Siping increases quantity of edges for gripping. Beveled lugs help prevent mud accumulation. Thin profile for flexibility and sufficient sensory feedback promotes better balance and grip.

Water Ready

All Astral shoes have a special relationship with water. Every component, from the thread to the laces are critically evaluated and chosen for its ability to hold up after constant soaking, to shed water, and not to accumulate funk. Many models have engineered drainage for water to come out while minimizing entry of silt.

Balanced Geometery

We believe that a foot’s position in a shoe should be similar to when barefoot. This allows excellent balance and biomechanically natural lifestyle.

Foot-beds are essentially level (only 1mm drop from heel to toe ) and provide medium arch support.  Tapered instep and heel area for better foothold and control. Wide forefoot allows your feet and toes to spread out for stability.


This G compound is formulated for premium grip while also providing "excellent" abrasion resistance. Its low durometer means the rubber is softer and therefore conforms well to the ground.

  • Perfect for Mountain Trails

    July 27, 2017

    My friend recommended these sandals, and she was right! They are perfect for our hiking around our mountain trails and they grip well when crossing water.

  • High Hopes

    June 05, 2017

    I bought these to use on my hike to Havasu Falls, in early May. The second day of our trip was going to Mooney Falls, and then on to Beaver Falls, which meant crossing a wide, but gentle creek several times. I bought the sandals because they could be used as a flip flop, or a sandal, and the glowing reviews included testaments to their grip on rock when wet. I broke them in at home, and did notice that the strap around the heel tended to slip, but wrote that off to my not keeping enough tension on them. At the campsite I wore the sandals to go to the pit toilets, and for comfort after wearing boots all day, and noticed the slipping of the strap again. I tightened them up, but they continued to slip. I was going to wear them to climb the trail, and ladder down to Mooney Falls, but decided to wear my boots instead. I wore the sandals on the hike from Mooney to Beaver falls, which is a fairly simple 6 mile (return) hike that crosses Havasu Creek 3 or 4 times. The strap kept slipping, so I tied a knot with the excess strap. It worked like a charm. The sandals were a little tight, but they didn't slip again. The strap between the toes, however, carved a pretty good line in one foot, but at this point it was the lesser of the two evils. Also, as to the grippiness of the sandals, I slipped a few times, post creek crossing. Nothing too dramatic, but my Teva-wearing companions did not. Frankly, I should have known better and left the sandals at home, but I had spent good money on them and was determined to make them work. I haven't worn them again, and it's been about a month. The scab between my toes has healed, so I'll probably remove the strap and wear them as flip flops. I had high hopes for these as convertible sandals, but they fell short of expectations. I already have comfortable flip flops, and wasn't looking for another pair. I hope you have better luck with them than me.

  • super rad but...

    April 25, 2017

    i hiked in them the second day i had them- on a trail with some rocks but nothing that rugged- and the sole peeled away from the bed about 1/4 down the shoe. that was a bummer because i bought these to use as my river guiding shoes. they are comfortable and good for hoppin' around on wet rocks or around a campfire. i lost one of the straps while walking one day (it kept coming slipping out of the gadget to keep it snug). other than that, these shoes are great. i guess they just weren't designed to be "all-purpose" like they are advertised.

  • Best flip flops ever!

    April 19, 2017

    Love these shoes! Great for walking both in and out of the water. We live near the Flint River and having good water shoes is a must! Not only are they comfortable and stable in/out of the water, but I get lots of compliments on the style. If all that isn't great enough, the customer service at Astral is the best. I called to see if I could order a new ankle strap (because I've worn them out a bit), and they are sending me new ones at no charge with free shipping! Customer for life. Just ordered my second pair in Grey/Eggplant!

  • Great Travel Flop

    October 19, 2016

    I've had my Rosa's everywhere from the bottom of the Grand Canyon doing wet and dry hikes, to going to the beach in Havana, Cuba, to hiking through the rainforests of Costa Rica. I like how the heel strap is optional, and easy to take on and off. I usually don't wear the strap, but find it's nice for a wet or muddy hike. Sometimes the sole is really slippery, but other than that I dig them. Lastly, they are great flop to transition from adventure to town. I often paddleboard in them and then go straight to the beach bar.

  • The best sandal I've ever worn!

    September 10, 2016

    Heres why I call them The best sandal I've ever worn!

    1. Durable - As I mentioned we wore them through it all and for four months of constant use. The shoes are still hanging on today despite all of this.
    2. Good Fit We loved how well they fit & stayed on our feet during river & muddy trail crossings.
    3. Light - The sandals are surprisingly lightweight, which was super important to us. This made it easy to add them to our backpacking trips.
    4. Floats - Along with being light it floats! This is good to know in case we drop them during a river crossing or while relaxing in a stream.
    5. Looks Good - Especially for ladies, a lot of performance sandals end up looking really beefy but these look good. This made it easy to transition from nature to city and wear the same shoe with anything I had on.
    6. Comfortable Despite being rugged & fitting snug enough not to fall off easily, the sandals remained comfortable for short hiking durations.

    FYI, I didn't ever really use the extra strap.

  • Rosas are made for me

    July 25, 2016

    I used to wear Chacos when I needed a sandal that could strap to my foot for river trips or working on the water. I hated my Chacos! The tan lines, the way the sand got caked up in the foot bed, and the straps never really fit my feet. I would always bring an extra pair of flip flops on river trips to change into right away.
    Then the Rosas were invented. I didn't want to write a review until I tested it on a 4-day river trip on the San Juan, which I wore them every single day. Then after the trip, I still wore them every day in real life. They are PERFECT! Rock climbing, wet rock wall swimming/scrambling, hiking, paddleboarding, and every day social girl life APPROVED.

  • Every Damn Day

    July 18, 2016

    I wear my Rosa's every day and have experienced any serious wear or flattening of the sole. They are super comfortable and the strap is a life saver for multi-day river trips when all I want to do is wear my flip-flops around camp.

  • LOVE my Rosa flips

    June 27, 2016

    I work as a guide on the Grand. I have worn a LOT of flips over the past 40 years and these are hands down the best flips I have ever used. They are comfortable--I have not gotten a single blister from the straps which have always been a significant issue with the other 3 major brand flips I have used. The footbed is comfortable and has enough support for all day hikes, all day wearing, every day. The soles are as grippy as any rubber out there--including 5-Ten. They are a tiny bit slippery in the footbed when wet but the pods with the extra grip do their job and keep your foot really pretty stable. They aren't the easiest to keep clean if you wear them 24/7 like I do but so what--these shoes are so comfortable it doesn't matter. If you want a work-horse flip that you can depend on to stay on and do the job, this is your flip. My other guide friends thought I was a bit overboard in my joy with these things until they got some of their own. I LOVE THESE FLIPS!!!! and my LowYaks are pretty awesome too!

  • Beach Block Beauty

    June 23, 2016

    My family's beach house is only a block away from the beach but it is on the wrong side of Delaware's coastal highway. My new Rosa sandals were perfect for the many trips that I make back and forth to the house everyday. They were secure enough for the occasional dash across the highway but light enough for the beach. They were also enough shoe to wear to bike all around the area. The blue color is beautiful and goes with everything. I am going to get several more pairs in other colors.

    I love this flip flop! First of all it is the cutest and most functional river-flop on the market. It has the support of a durable and quality shoe, a trendy unique style that does not scream granola and the stickiness of the best river booty. Style is important to me and it is nice to finally have a flip flop that I can wear to the river, beach, desert or any recreation venue and still keep up down in the city at a cool concert or night out. These flip- flops are more comfortable and functional than other high end flip flops (such as Chaco) yet, after a day of play I can throw a dress on and dance all night without being embarrassed for wearing flip flops to a wedding or nice dinner! As Yvonne Chouinard said, Why buy two pieces of gear when one will do the work for both?

    A friend of mine loves her Rosas so much that she sent me a pair! While the gorgeous red color adds to this flop's allure, I'm finding that my favorite feature is the spongy and supportive foot bed. Thanks, Astral!

  • Rock the ROSA or the ROSA Rocks....

    April 16, 2016

    Either way, you look at this flip-flop you will never kiss goodbye another flip-flop to the powers that be of any water deity when paddling in their home waters with the ROSA's "super strap" helping secure your footwear. Wasn't sure about the "practicality of the "super strap" but even when wet it doesn't stretch or lose shape and more importantly doesn't dig into the skin on your ankle. LOVE IT! Perfect footwear for any water sprite or supmermaid!! Trust me we know, we are on the water a lot and love the super grippy soles and the cute colors it comes in. We've worn this from the water straight to dinner pairing it with our favorite beach dress. Super light weight on your feet and don't make you feel clumsy!

    HOW INNOVATIVE!!!! The only " in between the toe " sandal that I have EVER been able to wear comfortably; I assume due to the design and ease with which to adjust perfectly! The option of on/ off strap very creative! GO ASTRAL!

  • wicked comfortable, but...

    April 08, 2016

    I have these in red, super cute, VERY comfortable foot bed, but there is a ridge between the ball of the foot and the toes that does not sit well on my foot. The ridge on the big toe is perfect, but under my other toes, the ridge sits back a cm or two too far, therefor is felt on the ball of my foot instead of resting under my toes as it should. Beyond that, great summer shoe, maybe eliminate that ridge to fit more foot types.

  • Flip flops you can actually wear all day

    March 24, 2016

    With high arches and an active lifestyle (mostly just chasing kids), I can't wear the flimsy flip flops from most stores. But I don't like the big, bulky ones. These are the perfect solution -- sleek and stylish, but with enough support and grip to get me through the day. I keep the extra strap on almost all the time, but I like that I can remove it for the beach. Love the grey color with a hint of colorful stitching.

  • Love! Love! Love!

    March 20, 2016

    Best.flip-flops.ever. Super light and grippy. Perfect for water activities, day-to-day wear, and travel. For those of us in our mature years the grip makes you move like your 18 ( ok...30). I stride right past those orange "caution - slippery when wet" diamonds posted while grocery shopping on wet days. Thank you, Astral!
