I am an avid hiker, but blisters are getting in my way. For the past 3 years I have tried every combination of blister prevention/remedy/treatment available over the counter. After a recent walk, just 1/4 mile into the walk I was starting to develop blisters. By the end of the 12 miles and application of 2 different treatments the blisters had grown to over an inch in diameter. Now, once again, I am afraid I will be out of commission utnil they heal and the process with start again with tender feet. I have tried a variety of shoe and sock combinations and nothing seems to help. Is a podiatrist a doctor that may be able to help with a skin inflammation on the foot? Do you have any personal recommendations?
