Luke Wymawrote a review of Salomon XA Pro 3D Trail Running Shoe - Wide - Men's on June 6, 2015
Familiarity: I've used it once or twice and have initial impressions
Fit: Runs small
I had the same experience as another reviewer here. I owned a pair of old XA Pro shoes (4+ years ago) which were not even a wide size, just the regular M. Those shoes fit good but I had to wear thin socks because they were just a touch narrow. Even so, they were my favorite pair of outdoor shoes I've ever owned.
I saw that wide ones were now available and thought maybe shoe perfection now existed for me. I bought a pair of the new wide model and they are so narrow that there is no way I could wear them. They are actually narrower than a pair of Solomon Sense (non-wide) shoes I that already have, despite being sold as a wide.
If Solomon checks up on these reviews, please make a real wide. These are narrower than your old medium size.
