this is a great boot. i ordered the stone leather in 7.5 but i'm sending it back for the 8 or maybe 8.5. i'm normally size 7.5-8 and the 7.5 for me is very tight in the foot but great in the leg.  my calf circumference measures 13.5" when flexed. the boot leg measures 13.75" at the calf and 15" at the top.  i would have just ordered the size 8 to begin with as i usually go up 1/2 a size in boots to allow for thick socks but i have a pair of timberland boots that look almost identical to these and i ended up fitting in a size 7 with room for an orthotic foot bed! i wore those boots every day for 2-3 years and i'm hoping to replace them with these. i would wear these every day. thanks to amazon for their free shipping and super fast delivery!!!
