After doing too much research my boyfriend ended up purchasing these boots because the price was right. Going off of others reviews he went with 10.5 (normally 10) and fit perfect. The toe box has plenty of room and width seems to be a true medium. Ankle support is adequate with no awkward pressure points. Has put a good Idaho Rocky Mountain 12+ miles on them scouting this past weekend with normal summer temps in the mid to high 80's with no sweaty feet.<br /><br />Only con thus far. THE SOLES. If you are planning on purchasing these boots having worn ANYTHING with Vibram soles previously, you will be highly disappointed. These boots have a foamish feel to them. The traction isn't as reliable like Vibram is. Great if you are stalking your prey somewhere WITHOUT rocks. You can defiantly feel everything underfoot. Stated earlier 12+ miles in two days and the soles have started to wear with small cuts as well.<br /><br />He is going to try them out for one more week and decide from there to return or make them a work boot.
