Many sports people and athletes will wear orthotic insoles to prevent injury and from getting arthritis they know that if they do develop things like that it could mean the end of there sporting career. Sports people have a increased risk of getting foot problems as they more regularly use there feet... in contrast to this obese people also have a increased risk of getting it because of lack of activity and the extra weight can cause extra pressure and strain on the feet. The arch or the foot is also more likely to collapse and tear which can cause plantar fascia because of the add weight also. All of these things can be avoided by just getting a pair of orthotic insoles.. remember it can also effect normal people as well.. nobody is immune.
Regular shoes have fitted in them regular insoles which are really no good at all because of their flat design which doesn't support the arch sufficiently enough. That why you must swap them for a pair of these orthotic or plantar fasciitis insoles at once! I did warn you anyway.. its now up to you to decide what you are going to do.
