Having blisters form on your feet is more than just annoying. The blisters can keep you from wearing certain shoes, working out as you wish, and even become infected, causing more serious pain. It's a lot easier to prevent blisters than it is to heal them, but first, you need to figure out why you're developing so many of them! Here are some of the most likely causes.
Your shoes are too big.
Shoes that are too wide or too long for your feet are likely to cause blisters because they move around and rub as you walk. Pay attention when you walk in the shoes you commonly wear. Do they slide up and down or side to side as you walk? Is there more than about ½ inch between your toes and the end of the shoe? If so, the shoes are too large. Consider buying a half size or a size down, and look try on some shoes in a narrower width to see if they offer a more snug fit.
Your shoes are not breathable.
If you constantly wear shoes that don't breathe, this increases your chance of developing blisters. Even if the shoes fit decently, you may develop blisters if you wear them for hours on end, causing your feet to become too moist. This problem is common in leather shoes that do not have any build-in vent holes. Try looking for shoes that feature some mesh and cloth inserts for better breathability. If you must wear non-breathable leather shoes for work, try taking them off for an hour or so at lunchtime or while you're sitting at your desk. This will allow your feet to dry out throughout the day so you don't get as many blisters.
You're not wearing breathable socks.
Cotton socks might be inexpensive and easy to disinfect in bleach water, but they're terrible for people who are prone to blisters. Cotton holds into moisture, so your feet get moist when you wear cotton socks all day. Opt instead of breathable socks made from nylon blends. Those made specifically for athletic wear are generally a good choice. If you prefer natural fibers, go with wool. It naturally wicks moisture away from your skin.
If you correct these mistakes and are still developing blisters, reach out to your podiatrist. They may be able to help you identify other issues that are causing your feet to blister.
