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!
