This shoe is smaller on the outside than my Shimano shoe, but has the same fit on the inside. When I took it out of the box, I thought for sure it wouldn't fit. But, to my surprise, it fit very well. I also like the dial that tightens to wire to snug the shoe to me foot.
I use these for spinning and am very happy with them. My feet are slightly narrower than average with a high arch, and these fit perfectly. The dial tightening system is effective and super easy to use. However the velcro strap on the toe is mostly ornamental. The shoes are stiff and reasonably light. I like them most because of the fit, the dial closure system, and the sleek, simple styling.
Use this shoe for Mountain Biking in all types of terrain and conditions. Very comfortable and provides secure fit when traversing rock, roots. Considering also using this shoe on road bike to eliminate multiple shoes and pedals.
