R Miller...The Bighorn is built on a wider last than the Tibet. The only problem I had with Tibets was that the forefoot was too narrow. When I went to Wides, the heel was too sloppy. The Bighorns fit my wide forefoot, average heel like they were made for me. Just an FYI on the fit of the Bighorn. The Tibet is an awesome boot and I tried like crazy to make them work, in the end, they just wouldn't work for me.
