Heel spur and good shoes
Making sure to wear good shoes is very important when it comes to treating your heel spur / plantar fasciitis. A wrong stance is one of the most important factors contributing to the development of a heel spur. A lot of people wear shoes that are totally wrong. Sometimes this is because people want tot wear fashionable shoes, or just because they choose for cheap, or a wrong sense of comfort (like slippers, which can be really bad due to lack of support for the foot). Next to heelspur they can even lead to other injuries, like back injuries. Therefor: take care to choose your shoes carefully. Make sure they deliver good support for the foot and ankle, some cushioning, and a good footbed. Also a raised heel can be beneficial, as it reduces the strain in the fascia.
Make sure the shoes allow for a natural way of walking. Shoes with a very hard sole, like mountain boots or safety shoes with a steel sole don't allow for this, so should be avoided.
High heels need to be mentioned separately. As a raised heel is known to be beneficial, high heels can even be beneficial for heel heelspur... However, in many cases, high heels simply put to much strain on the heel, and should be avoided.
Finally there are some brands that are specialized in making shoes with special footbeds or soles that can deliver relief. Some of the are Stretchwalker Fitflop and MBT. Some patients have had success with these shoes, but they don't offer any guarantee. Also quite some people had more complaints from heelpain. Some of these shoes have a round sole, which makes balancing on your feet harder. This forces the muscles to work more, but it can also put more strain on the fascia, which is bad.
