Featured is a True-Fit design wherein every element (boot liners to lace guides) has been handcrafted and engineered for a perfect fit. Added to that, there's an adjusted tongue that's been enhanced to wrap around the forefoot, therefeby reduces shell/liner stack-up. Note that this tongue is available in soft, medium, and firm flexing options. Overall the Coco hosts the basics needed (liner, fit, footbed), but it’s not recommended for use more than 10 times (at max) per year.
