Since I graduated to Real Shoes, Sidi Dominator is all I've used. I know for sure they go 50,000 miles without showing much wear or any change in fit or stiffness. Almost all the long distance riders here wear them. Maybe just to fit in? Or maybe not. I like the replaceable buckles and straps since I've had to replace them due to go-downs. Pretty much ruins the buckle on that side. I stock spares now. The MTB sole makes it possible to walk around normally.
