Thank you very much for viewing. These are popular GULL strap fins, customized specifically for drysuits, offering excellent weight, balance, and propulsion. Unlike rubber straps, the spring straps provide a stable fit and outstanding ease of putting on and taking off, ensuring comfortable use. Please consider purchasing. 1️⃣ Features ・Model customized for drysuit specifications while maintaining the performance of the MANTIS fins. ・Heavier specific gravity in the fin pocket sole eliminates the need for ankle weights. ・The boot pocket is higher than the MANTIS fins, and the spring strap allows for easy attachment and detachment.
