Based on the Zero Fear Boot the Shorts are made from dense leather upper for high abrasion with a durable rubber sole for traction while on the bike. Shift pad on toe prevents pre-mature wear during shifting. Excellent ankle protection and support. Slider is replaceable and does the job you suspect in a turn. This is a high performance short boot that is a great alternative to using the TIMBS (and easier to clean even in white) Made for the rider mind extremely comfortable when off the bike as well.
