This boot provides ankle stablility, is extrememly comfortable, lightweight and is correctly sized. I'm on my 3rd pair and each one has performed exactly as the first. I recently went on a "coast to coast" 100+ mile walking trip in Scotland and used this boot without a break-in period and suffered no ill effects, no blisters, no problems! I also wore sock liners and SmartWool medium weight hiking socks. Although the insert is adequate I have high arches and switched the insert to match my foot style.
