Love these shoes. They do a great job of controlling mild/moderate pronation. I've worn them on four ultra trail marathons (including two Wasatch 100's) and have been please. Just disappointed the dropped the XCR-free version. If you are running in these size UP. I wear a 11.5 street and wear a 12 (and 13 for 75 mi +)(if they made a 12.5 I'd be in heaven).
