Ronix One Boot Ceramic/Azure 2013 Articulating Cuff - The boot flexes with the rider without boot distortion. Double Last Fit - A double down bet that requires no luck: Ronix has perfected this process over the years to guarantee the best fitting boots on the water. Ronix's low profile and compact lasts eliminate excess material and deliver optimal energy transfer between board and boot. Ronix Intuition Foam - Genuine Intuition foam begins with only the highest quality raw materials. Stringent procedural controls are followed during manufacturing to ensure a consistently superior foam. The unique processing techniques employed produce a foam that has an unusually fine cell structure, which is very uniform throughout. As a result, tear strength, thermoforming properties of heat moldable foam (Intuition liners), and the pack out resistance (Intuition, Stage 1 and 2 liners) are dramatically improved versus traditional foam. There is also no filler added to these foams so Ronix can maintain the utmost quality. Double Stuff Footbed - Hard on the outside, soft on the inside - an underfoot combination rivaling milk and cookies. The double stuff footbed allows your foot to naturally cant inward without dictating a specific cant angle. Duratech Leather - Built to withstand the test of time, this new material is 4 times more abrasion resistant than traditional materials. It's applied to the tongue to prevent the laces from cutting and slowing long term wear and tear.
