Backpack Sierra often and bought these to replace some Vasque Clarions which fell apart. Usually carry ~35 - 40 pounds and go off trail. 35 days Yosemite and 140 miles this summer - miles of suncups, multiple water crossings and feet stayed dry/ nary a hot spot or blister with minimum break-in period prior.
Usually wear size 9 1/2 but on these, a size 10 fits better - thus 1/2 size larger?
Black boots look killer too -
Great boot and only con so far is cosmetic: There are two little, pewter/silver, rectangle, "gortex" badges, (one on the outside and slightly lower on each ankle - see picture above). After 100 or so most comfortable trail miles, looked down to see both badges now gone and leaving a small (but easily plug-able with snow seal?) hole on the outside of each boot.
