Hello. Heel Height: Since this boot is a trekking boot, it does not have a distinct heel height. The goal is to provide a balanced and comfortable walk on the terrain. Therefore, the height difference (drop) between the heel and the forefoot is generally low, and the heel height does not exceed a few centimeters. A specific heel length information is generally not given by the manufacturer, because the focus is on performance. Can be worn by women: Yes, women can wear these boots if they fit the size. Children's boots are typically made in smaller sizes, but some larger children's sizes may correspond to women's foot sizes. For example, a children's boot size 38.5 or 39 may fit a woman's foot of the same size.
