DUI was the first to develop a drysuit boot providing better durability, support & traction. Standard on all DUI drysuits, RockBoots™ can be worn with any wetsuit when combined with a wet sock. A must for any diver who walks, hikes or climbs to a divesite - even great on boat ladders! Available in men's sizes 4-15, they are sized to be worn with drysuit insulation.
