Giro Cylinder Mountain Bike Shoe (Black) (44)
The shoes worked well on my first ride with them. These are my first shoes with BOA I6, and I'm a little skeptical about their durability compared to the ratcheting top strap on my Specialized they replaced. I can't imaging that little cable is going to last as long, but I guess I'll see. I would prefer durability over micro adjustment. The ratchet was sufficient for me.

I would say the insoles were barely adequate. Just flat foam. I removed the arched insoles from my old Specialized and used them. Even after years of use they were in very good shape and better than the Giro's.

They look good and are light weight.

Overall, I probably would have selected something else if I weren't desperate for a replacement. Due to Covid the supply of options is very limited in my size (44), at my price point ($150).
