This is a fantastic very light shoe where you are constantly immersed in water but need serious gripping power that bare feet won?t provide. A typical use for this shoe is for crew of small sailing skiffs or catamarans where crew need to be constantly moving side-to-side across a boat to alter trim. Because they are so light and inexpensive, they are a great shoe for Jet-skis, the beach or just exploring the rocks around a beach Mens/Womens Size 6 TKA371 Size 7 TKA372 Size 8 TKA373 Size 9 TKA374 Size 10 TKA375 Size 11 TKA376 Size 12 TKA377 Size 13 TKA378 Size 14 TKA379 (Not recommended for rock fishing) They are slip-on, slip-off self-draining, with no-knot lacing.
