A better bootie. Hiyak™ offers superior stability, protection and insulation without the use of toxic neoprene. The result is a lighter, more durable, faster drying water-boot with phenomenal gripping powers.

"I'm lucky enough to call kayaking my job and paddle at least 5 days a week. Having the stickiest rubber on durable shoes is not just a bonus, but a necessity. I feel 100% confident in these shoes, from setting safety to scouting and portaging, and love the extra ankle support in the Hiyaks!"

"I wear these always and only. Massage. Kayaking. Stand up paddle. Landscaping. Walking. Sitting. Hiking. They are probably the best shoe I have ever worn."

"Actually the Hiyak seems darn near perfect for any water sport - sea kayaking, rivers, rafting, etc. I've used them exclusively for 7 years on long coastal SUP expeditions, and they have never let me down. After many years of blistered, soggy, sore feet, finding these was a god-send. I can't say enough good things about the Hiyak."

G.SS RUBBER™

Super sticky G.ss Rubber™ + Flex Grip™ outsoles adhere to wet rocks and boat decks like glue. Non-marking.

BALANCED GEOMETRY™

Zero drop, Level Footbed® + a wider toe box respects your foot's natural position while increasing balance and stability.

I just returned from a 6 night, 7 day paddling trip through Quetico Provincial Park. I purchased a pair of the Hiyaks just before I left and these turned out to be my absolute best purchase of the trip. We portaged several bogs and I hiked with complete confidence through the deep muck and over the wet boulders. Thank you, Astral, for the best water shoes I have ever worn!

WATER READY™

Quick dry, quick drain and lightweight, while reducing the entry of sand or silt.

NON-TOXIC INSULATION

Like neoprene, the 3mm quilted airmesh traps air between you and the hydrophobic shell.

MINIMALIST DESIGN

A low profile design providing maximum ground feel, conformity and flexibility.

HIDDEN LACES

There’s no better way to secure a shoe to your foot than laces. We've hidden them, to keep things tidy.
