What D3 says:
Finally a water ski boot that has been designed in the shape of your foot! An industry first, we molded an EVA foam toe for the ultimate in comfort. The Driver does not need to be uncomfortably tight to perform. Unmatched edge control with smooth, even forward and backward flex. The new Driver is the complete binding solution for the slalom competitor.
Inspired by some of the most successful snow-ski boots ever designed. The Driver gathers its performance from the molded flexing tongue. Ribbed for the perfect blend of support and flex the Power Flex TongueTM is the secret to the Drivers superior performance.
Easy entry and exit - Front lace and an elastic, molded rubber heel overlay allow for a competition fit with easy entry and exit.
Industry first molded toe piece a competition fit without sacrificing comfort.
Ultra-light weight - new materials allow for lightweight performance without the weight of rubber.
Low-friction speed skin overlay material - Eliminates water drag while in the turn. Also increases durability.
Front upper and lower laces to allow for a truly custom fit.
What we think:
A great boot. Very similar to the leverage, but a bit stiffer side to side and much, much easier to get into. The rear heal piece is stiff EVA that grips the heel well. The Flex Tongue provides more support than the typical rubber boot, but nothing approaching a hardshell. Overall, a great boot.
