As for keeping feet dry while in kayak....I don't know...my feet get wet from sweat. If its warm out, I paddle barefoot.
This is without doubt, the absolute worst piece of junk on market. Never ever again will I consider any of their products and when in store, will advise anyone near the rack to stay away. Pure crapola!
I was able to get a credit from the store and bought some Chota Mukluks. The Mukluks I recommend highly. Stay away from the Sealskinz.
