BMW calls the exoskeleton Biomex protection. Developed with the Centre for Orthopedics and Accident Surgery in San Moritz, Switzerland, it features a hinge that articulates the tough plastic framework on an oblique axis to mimic natural joint movement, which is supposed to protect your ankle joints from the sort of painfully unnatural movements involved in falling off a motorcycle. There's also stout shin armor, form-fitting plastic caps to protect toes and heels, as well as a washable, shock-absorbing insole to soften the blow if you have to put a foot down hard. Altogether it's sufficient protection to earn CE certification, something not as common on motorcycling footgear as you might think.Getting your hoof inside is easy. Secured by two lateral panels of hook-and-loop material, the front of the boot swings forward to reveal a nicely padded interior, complete with sweat-absorbent padding. Snug up the internal speed-lace system with one tug, pull the wraparound shin-guard back in place and you're ready to ride.
