What is a blister?
A blister is a pocket of fluid in the upper skin layers that is usually a response to either injury or friction. Blisters on the feet are very common.
Fluid collects under the damaged skin, cushioning the tissues underneath. This protects the tissue from further damage and allows to heal. Most blisters are filled with a clear fluid (serum) However, may be filled with blood (blood blister) or pus if they become inflamed or infected.
What causes blisters?
Blisters form due to friction between your skin and your shoe. Poor fitting shoes, or shoes that don’t conform perfectly to your feet, will increase the chance of blister formation.
When new shoes are purchased, wear them for half an hour, take them off and check for any red marks. These red marks will indicate where blisters may form.
As blisters form due to pressure and friction Misaligned feet are a major cause in the development of these.
This may mean having to have regular foot checks and apply moisturisers to keep the skin soft, while this may seem counter-intuitive, softer skin provides increased resistance to blisters. You can take further measures to decrease the risk of blisters by choosing well-fitting socks made from a suitable technical fabric. Additionally, choosing well-fitting shoes that are suited to the sport or task that you are doing is extremely important and should not be overlooked. It is important to make sure of the lace locks if they are available to decrease the movement of your feet inside the shoe.
