I think most scale their heel heights, but I can't tell for sure because I'm close to the standard size anyway.
Last week I wore my Hot Chicks twice at home, and yesterday took the chance to wear them out.
At home I didn't really feel any difference yet, but yesterday was kind of an success. They felt a little more comfortable and it also was the longest distance I ever walked in them.
At the end they got really uncomfortable, but I'm glad I wore them out once again and very motivated to do it again soon 🙂
