I typically wear a size 7, 5.3 and very athletic - right calf measures bout 15 1/4". The reviews here are conflicting - esp w the Tae Kwan Do sparrer claiming she's got 17" calves and were able to fit into these shoes. I ordered the 6 C/D, and 6.5 B to not take any chances as the reviews for comfort (for walking) were astounding.

Quality of the shoe is very good. Sturdy and robust, rugged leather (beautiful). If not for the fit, i would hv wanted to other the other color as well.

Size 6 C/D - Shaft ends 2" under the knee cap. I could fit this after a tug, but couldn't zip up the shaft leaving bout 2" unzippable. This felt snug, comfortable.

Size 6.5 B - Shaft ends 2" under the knee cap. I could fit this after a tug. On the first attempt i couldn't zip up at all (leaving bout 2" unzipped. Adjusted the strap to the widest configuration. Tried, no luck. After reading the description i retried zipping (more like forced zipping) and was able to zip up the entire way - however, it ate into the flesh of the calve. No way i could get jeans or leggings into this at all. After i zipped it up, i did notice what the other reviewers said that the bottom of the shaft (right above the ankles to mid calf section) 3 or 4" of flopping - ie i hv a feeling this happens to well defined calves & potentially shorter legs - ie shorter people)..

I REALLY REALLY Wanted to keep these. I don't know if anyone else have the same calve tightness fit and was able to successfully stretch the leather out to finally fit jeans inside the boot ? (anyone has had any luck ?) I would love to keep them and wait it out as i think these boots are worth it. Otherwise, they are both going back to amazon. Sigh.
