Manufacturer's Description refers to the men's version
The Dyno features an anatomically-designed footbed with significant arch support and a sculpted heel cup, topped with a textured no-slip layer. Below, two densities of EVA give long lasting support and cushioning. A lugged outsole, made of non-marking high-friction carbon rubber, gives outstanding, trail-worthy traction.
The Dyno has adjustable tubular webbing straps that secures the fit and hold around the toe and across the foot. Its metal buckle—reminiscent of climbing hardware—allows the wearer to tighten the Dyno’s continuous webbing loop as they please—tight for control and performance, or loose for flip flopping around.
Here's what other sites are saying:
The Dyno flip flop offers a customized fit with the adjustable tubular webbing. The webbing can be adjusted around the tow and then locked into place with the aluminum buckle. Adjust it once and enjoy the customized fit for every other time you wear them! The bottom has a well defined arch, nice heel pocket, and wide forefoot platform. The lugs are multi-directional for incredible traction.
