The Senna is a fully-molded driving moccasin dubbed after influential F1 racer Ayrton Senna. It features a Skylite™ EVA Outer with a fixed SuperCush™ EVA Sockliner, rubber traction pads, and removable laces strategically incorporated for added functionality. It is comprised almost entirely of this super-light and supremely comfortable foam that’ll be very useful for long drives.
