These have been key to keeping the outdoor miles going on the road. Adding shoe covers to my road shoes just wasn't cutting it. These keep my feet warm and dry in temps down below 40F and would easily handle more with toe covers and some toe warmers.
Sole is stiff and transfers power well. The Sidi boa allows for a good fit to accommodate my Solestar insoles. Added warmth and protection around the ankle is not too tight for when thermal bibs have a rear zipper that extends into the cuff.
