Adidas 3MC Black/White/Black Sole Vulcanized Details EVA Sockliner Geoflex Outsole Metal Eyelets Textured Midsole Wrap SOLE Vulcanized - “Vulc” shoes are light, flexible and break in quickly. These don't provide as much foot protection as cupsoles, but they are preferred if you’re looking for good board feel in a shoe with less weight and bulk. DETAILS EVA Sockliner - Similar to the PU sockliner, the EVA sockliner hugs your foot, adding much needed cushioning and support. Geoflex Outsole - Geoflex is an innovative tread pattern that provides superior grip and unmatched flex resulting in greater control and board feel. Metal Eyelets - Metal rings are used to reinforce the eyelets for durability.
