i need to replace my shoes, but i've only ever ridden Sidi's (since 1998), so I have no idea what else might fit and wear well. I own Sidi Dominators (regular width) - does anyone know of a comparable, but less expensive shoe? I need narrow and fairly stiff with a decent arch. also, since i've been riding my RFX more and single speed less, i'm doing a bit of hike a bike- would be nice to have a decent sole on there. Thanks. Oh, must be SPD compatible.
