In most cases skin peeling is nothing but a short term annoyance and it does pass in time on its own. You probably stated the true cause of your troubles – high perspiration because of tight boots. But, you have to be aware that skin peeling might also be the symptom of some other, not so light condition. Please, check your status with the doctor, that is the safest way.
Hmm, I suppose that you already know what my advice to you would be. Do not play with your health! If there is something wrong with your body, fix it on time, it might be too late when you decide to go to a doctor. Well, I think that in your case, it is nothing that serious, but really, you must find some time for yourself and your health troubles. Probably, it is nothing more than urinary infection, but doctor has to confirm this.
