MY size for this model of hiking boots is 10, the  toes feel better; also I am size 9.5 in timberland Chocorua, size 9.5 in Columbia Master of Faster, size 10 Vasque Talus, size 9.5 in Nike running shoes.  I am 5'8"  175 pounds
Very comfortable for being a hiker with a backpack up to 40 pound. After 12 hours of hiking on unstable, steep, wet and rocky trails, there was enough ankle support to prevent foot and ankle fatigue.
The stitching and construction are high quality. Short breaking period. They are truly waterproof.  Good grip on mud, wet rock and good performance in any trail.  Good toe protection.
