The Kestrel is the stiffest shoe that Five Ten makes. It's built for aggressive trail and cross-country riding with super-efficient pedalling. The BOA Fit System is quick and easy to tighten and even quicker to pop open and take the shoe off. A minimal XC-style tread pattern saves weight while providing plenty of traction but there's a handy patch of rubber behind the cleat recess for pedal grip when riding unclipped.

If you want to direct every ounce of power you produce into uphill progress and have a comfy secure shoe for bone-shaking descents, the Kestrel BOA should be your go-to bike shoe.
