Flex Grip Outsole

This rubber allows excellent flexibility and sensory feedback for heightened grip and balance. Maximized surface area for high friction on smooth surfaces. Divided lugs for substantial grip on loose dirt. Razor Siping maximizes edges that bite into surfaces upon flexion. 

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.


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.

  • A fabulous water shoe!

    September 14, 2021

    I bought a pair of the Loyal AC's while on vacation in MA, just knowing that I would eventually need them on a hike. Well, the next hike I did where water was involved just happened to be in "The Narrows" otherwise known as the Virgin River in Zion National Park! Water depth where we walked was between mid-calf to the top of my legs! These shoes were absolutely the best, most comfortable water shoes I have ever worn.
    Good job Astral!!

  • Perfect update to a solid design!

    July 15, 2020

    I have used the original size 14 Loyaks since 2017 and they are just now starting to show holes in the soles. I honestly think that Loyaks are the most DURABLE shoes that Astral makes because the soles are sewn into the uppers, not glued. The new Loyak AC have an improved lacing system, better drainage, and dry very quickly. The material is superior to the original model, which is still a classic. These are an excellent pair of river shoes and I hope they last as long as my original Loyaks did.

  • Even old guys can love these shoes!

    July 05, 2020

    I found this company in the Orvis catalog, but Orvis only had one style. I emailed the company asking about different styles. They contacted me immediately. I asked did they have a shoe for my husband who likes to sail, likes to walk on the beach (without going barefoot), often getting his shoes wet and can be more of a slip on. The customer service gal pointed me to the Loyak style. I felt the Loyak AC was best for my husband in terms of water drainage and drying capacity. I was very concerned the style might be too contemporary for him, but he LOVES them! This is a submarine naval officer who at 66 likes the comfort of what is tried and true. I am grateful to Astral for designing a well fitting, superbly comfortable shoe that DRAINS too! I was very happy to place his Sperrys on the partial use shelf. Now it is my turn to shop!

  • Lightweight Casual Water Shoe

    July 07, 2020

    I used this shoe mainly as a casual shoe around town. I really enjoyed how lightweight and breathable the shoe was. But do understand this shoes purpose. Its not designed for whitewater use, but I think it would still survive the average single day raft trip. This shoe is basically a stylish version of the water sock shoes that I wore a lot as a kid. Great option for casual water use.
