"I'm guessing this is for a cold climate? Ain't no way in hell I'm wearing neoprene boots over my nice leather kicks in summer. They'd be destroyed from the sweat. Cycling feet need to breathe!I think they'd also need more than just one big leather strap over the foot as when you pull on the upstroke your heel or toe would lift through the neoprene as it's not a static material. Spread the load wider so there's no hot-spot on the foot. Think more oversized sandal and you could be onto something for summer."

"I'd say it's taken away so they can quickly replace it with another sharp blade and get the machine working again while they're sharpening the blunt one."
