These are exactly what I needed. I ride year round in northern Colorado. Since I usually wear my Luna running sandals, I needed something that could fit over the sandals to block the wind. With the heel strap, these toe covers stay put. So why only 4 out of 5 gears? Because I question the durability. The fabric where it wraps around on the bottom is showing a lot or wear. But maybe I walk around in them too much, since I mainly bike to commute and run errands. I hope to get more than two seasons out of these. If I do, they'll have earned that fifth gear.
