Hello , I've also been plagued with excessive sweating of the feet since my early teens and have tried many different " Solutions" without any positive results .I went for years changing socks and shoe several times a day .Hyperhidrosis was really controlling my life a negative way . five years ago I came across an article about Iontophoresis and decided to give it a try . I did the therapy with an Idromed 5PC every day for the first two weeks without any noticeable results and suddenly on the 18th day of therapy I noticed that my feet were dry! I couldn't believe it , I could wear sandals without slipping and sliding in them ! It changed my life! I can recommend trying Iontophoresis to anyone suffering from excessive sweating.
