Blisters occur due to the friction of two surfaces, much like rubbing your hands together to produce heat. If you have ill-fitting shoes, it can cause a lot of movement of the feet within the shoes and cause friction which results in blisters.
Furthermore, after repetitive blisters the area can have hard skin form over it (callus). Podiatrists at Healthy Steps are well-educated in blisters as we treat many patients who do events such as the Auckland Marathon, Coast to Coast and the Oxfam Trail Walk. Blisters occurring is a common complaint with many sporting activities.
Socks are very important with blisters. Cotton absorbs and holds onto moisture which is similar to sitting in a spa or a bath for a long period of time. The moisture and heat softens the skin and consequently, any friction over the area results in a blister. This is why it’s important to get one or two pairs of proper walking or running socks to help keep your feet as dry as possible, and provide a suitable barrier between your foot and the shoe.
What can healthy steps do for you?
- We assess your footwear to see if it is matched to the way you walk or run and if it is designed for the activities or work you are doing
- We remove patches of hard skin (calluses) as they can become pressure areas which result in corns or deeper more painful blisters
- We can educate you on appropriate socks
- We can show you how to dress the areas of high pressure to stop blisters from reoccurring
- We can suggest specialist creams that can help prevent blisters occurring
Key note: Blister plasters that stick to the blister may help during activity but can hinder the recovery when you peel them off.
