The soles are unique. Better than any sole heel spur which is offered in a deposit-taking business. In business they advertise indiduell matched deposits, but have only a small opening for the heel spur, which does not always sit well. These deposits of all hacking is very soft and the zusäützliche padding is great. In addition, the sole is still not as thick, just not at the front, and so it will fit in any of my shoes. They can be individually cut to size for its own good size. The only drawback, after waschne in the washing machine, the upper material part of the lower front has solved anything, so better hand washing. Otherwise the sole heel spur is really highly recommended!
