Kayak fishing coastal Louisiana. Paddle boarding Kauai’s Hanalei Bay. Raft runs on California’s American River. The contemporary “boat shoe” is definitely more adventurous (and aggressive) than its predecessors. When the wet won’t quit, Simms’ Mariner Shoe combines non-absorbent, perforated upper materials for quick draining and drying. And its fully enclosed design keeps your feet protected, while kicking sharp rock and nasty debris to the curb.
