    I coordinate a project focused on building trails all over Panama. By trails I mean aquatic and terrestrial. These boots are the only ones I need for MTB, kayaking, pack rafting, canyoning, caving, hiking in mud, beaches, highland mountains or jungles. Rad support, grip and most importantly for the tropics they actually get drysh over night and dont implode in 6 months!! My only request, give please us one more color!!

  • Wonderful Boot

    October 29, 2021

    Earlier in the year I tried a pair of Pisgah MS boots. I loved the gray no nonsense worker look, the grippy sole, zero drop and locally made (I live in Asheville), The Pisgah boot just wouldnt work as I have a high volume foot - both wide and a high instep. Regrettably, I had to return them. It was a sad day After wearing out another brand over the past year I was looking for another pair of boots. I saw these at Second Gear and tried them on. They seem to have more room than the Pisgahs. My toes wiggle freely and I have enough lace to tie them up without feeling them push into the top of my foot. These are my work boots. I often am on uneven terrain, exposed to a goodly amount of water and climb ladders. The shank helps to keep my foot from curling around the rungs and it is structured enough so the rails of the ladder dont bruise the sides of my foot. I feel confident in my purchase if I am looking up and moving while on a slope with differing surface. On flat surfaces my foot is comfy and planted on the ground with no lift to shift the angle of my hips. The grip is Marvel Comics grippy. They are are also well made. It seems like they will last a good long time. I am really happy. These are a blue ribbon winner!

    These shoes are most excellent. I took them on a ten day trip to Hawaii where we did a ton of hikes in wet, muddy terrain and they were fantastic. Excellent grip, they drain well, and they are very light. I brought my backpacking boots with me as well and I barely used them because of these. I did put some insoles in them, but I do that with a lot of my footwear. I will definitely be using them throughout the summer!

  • Great Boots!!!

    July 01, 2019

    I have worn these boots daily 09/2017. They are great boots; very comfortable standing all day at work. I do a lot of hiking, mountain biking, and backpacking. These boots must have 220 miles in WNC and Colorado. Very rugged and tough. Theyve held up great and well worth the price. Thank you Astral!!

  • Grand Canyon - Rim 2 Rim

    June 03, 2019

    I bought these boots from a small shop in Saluda, NC while on vacation 2 weeks before my Grand Canyon trip. I worn them that weekend in NC and put about 7 miles on them. I was impressed with the lack of hotspots and just the overall quality of the boot. The boots gave me so much confidence that I took them on my Grand Canyon trip and put 30 miles on them and not one hotspot or issue with the boot. Incredibly stable and dried super fast. I highly recommend these boots.

    I got these shoes for work as I do a lot of standing and walking. I have spent probably $500.00 on different types of shoes and the TR1 mid rise are the best shoes I've ever gotten. Thank you Astral.

  • Great Shoe

    March 29, 2019

    I suffer from Morton's neuroma, a very painful toe condition. Some shoes I have cause me a lot of pain, but not these. I am confident on back trails as well as on flat trails. Highly recommended.

  • Best work shoe ever! Though I had meant to get the water boot

    February 18, 2019

    My feet| love your designs Astral with comfortability, light weight, derable and little water absorbing to the boot. Though I've only had them a couple of days Astral team has proved themselves with the water mid-top shoe I bought a year ago lasted outstandingly the whole while! Thank you for the quality flat footed shoe. Although I realized that this was not the exact shoe that I needed it is still flat-footed to make my feet feel at comfort. This boot holds an amazing grip ranking above the water shoe though both posessing excellent grip.

    I do plan to purchase the Hiyak High top water shoe for the flat foot and I will be buying another as a gift.

    Would it be possible to receive ASTRAL promotion bumper sticker with my next purchases? Thank you!

    FYI if Astral team is interested I called every shoe shop in ABQ NM area and none of them had ever heard of Astral. Maybe they can be brought here if the opportunity arises.

    Thank you ASTRAL TEAM!
    Keep up the great work!

  • Flat pedals rule!

    December 13, 2018

    After considering all my other options for a new riding shoe, I decided to go with the TR-1 Merge. Appealing are the sticky rubber sole and the light weight. I've been riding in my Astrals for a full year now, and not only are they fantastic on my flat pedals, but they have held up far better than I expected! I really love how breathable and quick-drying they are, and when the trails turn into hike-a-bikes, the Merges offer superior traction to anything else I've owned.

  • Another hit from Astral

    November 21, 2018

    I have been hiking in the TR1 Trek for several years now, hiking in everything from snow, mud, sand, rocks and water! I absolutely love them and have probably hiked over a thousand miles in them. This past weekend I decided to try the Merge, just to see what they were like and hoping for a warmer heavier duty alternative for winter hiking. Straight out of the box, I put these things through 77 miles of rough Appalachian terrain over the course of 3 days. They performed just like the Trek! No compromise on weight, slightly warmer, and the same agility I love out the TR1 platform. Can't wait to keep rocking these all winter!

  • Awesome shoes

    September 22, 2018

    Best water shoe I've had! Owned them for about 4 months and wear them everywhere, on land and water. I like the removable insole and it also allows the shoe to dry quicker. Great ankle support and comfy foot bed, the sole has good traction and serves well in slippery areas. I'd recommend sizing up a half size and maybe more if you intend to wear a drysuit with neoprene socks. Overall well built and designed, so far they've held up great with no seams ripping like some past shoes by astral. 10/10 would recommend.

  • Love them!!! But..

    May 28, 2018

    These are great! They really are. However, my only wish would be that they were a little more like a true mid-top version of the TR1-Treks in that they incorporated a little more mesh for ventilation as my feet tend to get pretty hot. May not be an issue for you but it does make this shoe sorta useless for me in the warmer months. Through fall and winter though this boot is absolutely fantastic! Way way way comfy!!! And VERSATILE! I travel a lot. Often working in big cities and incorporating outdoor activities when I can. Recently had to work for several days in Toronto, Canada. Decided to road trip it up from North Carolina and spend a couple nights back country camping on the Appalachian Trail in Virginia and Pennsylvania along the way. I like to pack light and this shoe was perfect for both. I could comfortably backpack several miles from the trail head to the nearest lean-to in the AT and also pound the pavement in the city for several days. The low profile is great. When wearing long pants just looks like youre wearing a sneaker, not large obnoxious hiking boots that look completely out of place in an urban environment. Would definitely recommend if you like transitioning from town to trail with quickness and ease.

  • Traipsing onward in these earthly Astral plains . . .

    May 15, 2018

    About a year ago on this site, I raved about a pair of Brewers I'd recently bought, and soon after I purchased another pair of Astrals, this time a pair of Rasslers, which might well be at the moment one of my favorite just slip on w/ loose laces OR get serious and tie-up pairs of canvas shoes -- for a number of reasons I won't go into too much here because those nifty multi-purpose critters are not available anymore on the Astral site. So in my next search for an Astral, I opted for a pair of TR1 Merges, which I like a lot, but they seem to be cut just a tad narrower and shorter than the Rasslers [both are size 10 -- maybe I'll try a size 10 1/2 for the next pair of Merges.] That means thin socks or no socks for the present pair. Either way, the Merges have become a great motorcycle shoe for me, as well as paddling shoe, general light work shoe, and comfortable hiker. And I do appreciate the ankle support being higher in the Merge than the Rassler -- though not enough to give up my ultimately favoring my Rasslers! So bring that shoe back, Astral, please?! Meantime, the sole on the Merge makes for extremely sure and flexible footing -- always a good combination.

  • Supportive lightweight hikers!

    May 10, 2018

    Had my Merges about a month now and I love them. Great for hiking and everyday use. Also great for multi day hike in kayak expeditions. I wear them for everything from work to kayaking and hiking.

  • Great shoes, but small

    September 27, 2018

    I have Loyak, size 10, love them very much for kayaking and ware activities, also have Tr1 Junction size 10,5 and use them casually, like them very much, too. For multi-day kayak adventures in colder weather or with hiking parts I decided to buy merges. I bought size 10,5, assuming, it would fit more loose than Loyak and more like Jumctio to be able to have a neoprene sock. As it turned out, even without socks Merge 10,5 have less room and are shorter, the Loyal 10. And removing the insole in Merges doesn't help, because the inside of the boot is different from other Astral shoes, there is no rubber layer under insole, just fabric and seems. Besides the size, the shoes are very durable and good looking. The sole is very grippy, the lacing is very secure, they dry relatively fast and look casual enough for city walking. Recommend them, but buy at least half size bigger, than your regular shoes or other Astral shoes.
