i was a little dubious about getting these boots,even though all the reviews were great. my main worries were about the calf width,as i dont have the skinniest. i also hate breaking in new shoes and boots,last pair of boots i bought i still cant wear them as they hurt my heel area.these are fantastic,a little tight to begin with,but no discomfort at all,no blistering.. the middle area of the back panel is also slightly elasticated,which was ideal for my bigger calf area. as for sizing i am usually a 6 or 6 and half,i got these in a six,and they are fine. they are also extremely comfortable,which is a bonus.best buy in boots ive had for years.
