Designed to be used with all BARE drysuits equipped with compression-resistant soft boots. Excellent support for rocky shore entries, boat decks and boat ladders. Velcro ankle closure, thumb loop and fin tab. Durable toe and heel cap. PLEASE NOTE: These are sized to wear over soft boots (i.e. these are made larger, to accommodate wearing soft boots under them - if you are using size 10 soft boots, order size 10 trek boots). This fantastic pair of boots is a great addition to your drysuit. Protect those feet on rocky bottom sea floors and keep them warm when paired with soft boots.
