This Klim Blak Jak Leather Boots review examines full-grain leather riding footwear with a Michelin rubber outsole and XRD impact-protection foam. A welted sole, metal lace eyelets and a removable insole accompany the casual-looking design.

Lace fit and XRD padding
The Blak Jak uses metal lace eyelets and an entry-assist pull loop. Klim lists 3mm XRD foam at the tongue and ankle pads, along with reinforced toe and heel construction. Set the lace tension in your riding socks, then check heel retention and pressure across the instep. Secure the lace ends before trying the motorcycle controls.
Lining and weather expectations
A breathable, moisture-wicking antimicrobial liner is specified, but the checked listing does not identify a waterproof membrane. Consider rain requirements separately from the leather appearance. Follow the care instructions for the upper and lining, and allow the footwear to dry as directed. A casual style should not be taken as evidence of suitability for every riding condition.
Michelin sole and left-foot shift pad
The Michelin rubber outsole uses welted construction, with a midweight lasting board and removable insole above it. The asymmetric shifter pad is specified on the left foot. Check the sole on your pegs and the toe beneath the gear lever, then try an indoor walk. Assess fit with the original insole before considering a thicker replacement.
Protection and construction
The specification lists protection at the heel. Check that these areas sit correctly when you adopt your riding position.
Versions and options
The checked listing links to these options: Gunmetal Black, Tanner Brown. Check the selected version and available sizes before ordering; the linked price may apply to a particular option.
