Optimist hiking straps hold sailor’s feet when hiking and absorb individuals’ shocks from rough sailing. Our straps are made of 600D Polyester with PVC backing. They are filled with NBR foam in the middle for water resistance and pleasant feel. The straps are put together on their one edge, so as to adjust them according to the length of your feet. The straps are loose on their other edge to tie them on your Optimist using a plate or buckle.
