I've just received back two pair of shoes that I sent to Yosemite Bum. Prices and turn-around time were just what they said they would be (half soles and rands came in at $47 ea.) One pair was a pair of Scarpa Marathons (a discontinued model) that I use extensively in the mountains and on extended climbs. These fit so well that they're now on their third set of soles. They were in need of repair to the uppers as well as revitalizing the bottoms. The other was a pair of Acopas. I'm willing to pay ca. $100 for the resoling of these shoes since neither is replaceable.
I've tried the Scarpas and the fit continues to be as comfortable as before the operation. I haven't climbed in the Acopas yet, but when simply trying them on again, they seemed to fit pretty much the same as before.
Of the two sets of shoes I've sent to YosBum previously, one held up very well. The other began to show some delamination around the toe area of the soles as they became worn down. In a phone conversation, YosBum told me they would repair the soles, but at that point they really needed replacement.
Overall, my assessment is positive, but like Empi I'm also interested in what others have experienced with resoling.
