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 Geometry

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.


The “ss” is for “Super Sticky” and we can confidently say that outsoles made with it provide the best grip in water-sports. Unlike other maximum friction compounds, G.ss is non-marking and provides good abrasion resistance. Its low durometer (measure of hardness) lessens impact and provides excellent conformity to surfaces.

  • Great Grand Canyon Shoe

    May 06, 2019

    I needed a good all-around shoe for a 21-day Grand Canyon trip. These worked great for chilly mornings on the raft, with my drysuit in my kayak, hiking up stream beds, as well as canyoneering (scrambling up slot canyons, rappelling & rock climbing) with their super sticky soles. They dried quickly each afternoon (although everything does in the desert). A guy on my trip also bought these for the trip and our only complaint is that both of us had rubbed bloody spots on both of the backs of our heels after the first big hike because the back of the high-top part is pretty hard until you wear them in a bit. Loosening the laces and wearing socks that are taller than the back edge seemed to help. I usually wear a women's 8, I ended up with the men's 6.5/women's 7.5 as I felt they ran a bit big. These will be my new kayaking shoe and look cool enough to wear around town too!

    These shows might be great in the water but I love them on my mountain bike! They are sort grippy to the pedals, ankle protection without restriction, minimal to no bulk and they hose off and dry overnight!!!!

    The Rassler is Awesome! Highly recommend. Rassler 2.0 fits truer to size than the old one did.

    First of all this is my second pair of Astral shoes. And I must say, I will ONLY buy Astral shoes for all my three season activities. I use this shoe for fly fishing, mountain biking, and even hiking. It's also a great approach shoe when I'm heading out to the local crag. Great water shoe, although takes a while to dry. My only complaint is the heel loop broke off on one of the shoes after about a month, and I wasn't even tugging on it very hard. Now I'm contemplating cutting off the other to even it up, which I'm not stoked about. For that, I'm taking away one star.
