Astral Clearance Hiyak Shoe
OVERVIEW
The Hiyak is Astral’s view of a proper bootie. It offers ground-conforming stability, foot protection and insulation without neoprene. The result is a lighter, more durable, fast drying water-boot with phenomenal gripping powers. FEATURES
Flex Grip Outsole
- This rubber allows excellent flexibility and sensory feedback for heightened grip and balance. Maximised surface area for high friction on smooth surfaces. Derived lugs for substantial grip on loose dirt. Razor Siping maximised edges that bite into surface 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 to constant soaking, to shed water, and not to accumulate funk. Many models have engineered drainage for water to come out while minimising entry of silt.
Balanced Geometry
- Astral believe that a foot's position in a shoe should be similar to when barefoot. This allows excellent balance and a bio mechanically natural lifestyle. Foot beds are essentially level (only 1mm drop from heel to toe) and provide medium arch support. A tapered instep and heel provide better foothold and control. A wide forefoot also allows your feet and toes to spread out for stability.
GSS
- The "ss" is for "Super Sticky" and Astral 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 provide good abrasion resistance. Its low durometer (measure of hardness) lessens impact and provides excellent conformity to surfaces.
