What's unique about the Thor Ratchet Boots available from Riders Discount is these are the first boots to offer a ratchet strap closure system. Simply ratchet the lever until you have the boot as tight as you prefer, then push down on the release to loosen the strap when you're done riding. Constructed using a leather chassis, the Thor Ratchet offers positive feedback while offering great protection via shin and ankle impact plates. A welted rubber outer sole with a steel shank insert offers you maximum support on the pegs. The Thor Ratchet boot is available in black or white in sizes 7 to 15 US. If you would like to place an order or have any questions regarding sizing, please feel free to contact MIKE at 866.931.6644 ext. 804 or send him a message through this forum.
