Tom M.wrote a review of Five Ten Kestrel Pro Boa Shoe - Men's on May 28, 2020
Familiarity: I've put it through the wringer
With almost thirty years of MTB, I've gone through multiple Sidi shoes and boots that were great but then decided to do a trans Alp. After reading several reviews, bought this and the NW Spider. specifically to address the hike a bike, something that never usually entered into my repertoire. BLUF is that the NW were much better suited for that task but this review is for the FIVE TEN. I liked the lacing system ease of use for getting in and out of the shoe. The fit was good, about the same as the Sidi Dominators but the problem comes with the sole stiffness. It is a very clunky sole that does not bend, (I weigh in at 115Kg body and pack) and therefore during a hike a bike, my heels came up out of the shoe, not what I want in the Alps. The Dominator comes with a heel adjustment so that at least during a hike a bike your heel is held in place as you stiffly climb those 30% grades. The heel stays in place on the NW but that has a different retention system. I'm a Candy guy, and the cleats need the spacer to allow you to click out quickly. Otherwise, you're almost welded to your pedals.
Overall, the shoe is satisfactory as long as you stay in the saddle. With a stiff sole the power transfer is about as good as any of the Sidis I've had, though a bit more comfortable in the fit. Walking in the shoe is little different than with the Sidis with the same clomping except perhaps with more surface area on the FIVE TEN I didn't feel unsafe while walking on wet pavement. The cleats can be set up to remain below the tread, so no surface damage or risk of sliding on tiles. It's a shoe that looks and acts great while you're in the saddle, otherwise, it's not hike a bike compatible.
