Blisters have long been a source of misery for runners and other sports. Blisters may be very painful and incapacitating, yet they are often underappreciated. Blisters were formerly believed to be produced only by friction and pressure, however this is no longer the case.Do you want to learn more? visit
It’s critical to know what a blister is before you start treating it. A blister is produced by shear between the skin and the underlying bone structures, which causes damage to the deep layer of skin cells. Shear happens when two things have enough friction that when a force is applied, it slides over the less resistant underlying object. If you attempt to slide down the seat of a leather sofa in your shorts on a hot day, your skin will cling to the leather and you will only be able to move as far as your skin can stretch and distort. Shear is the term for the deformation that occurs inside your skin. When there is no sliding between the skin and the sock/shoe, a blister forms. Instead, the skin slides against the bones. The shear becomes unnatural and harmful with time, especially with side-to-side foot motions, causing the injured region to fill with fluid. An abrasion occurs when there is slippage between the sock/shoe and the skin. Only the top layers of skin are damaged by abrasions, which frequently result in a red raw wound. Poor-fitting shoes that enable the foot to move inside the shoe are a frequent cause of this.
You may be asking why it’s so essential to know what causes blisters. We can avoid blisters and treat them better if we understand why they develop. The main aim of blister prevention and therapy should be to figure out what’s causing the blisters in the first place. Blisters on the back of the heel are often assumed to be the result of the heel moving up and down in the shoe. According to new research, heel blistering is often caused by the heel bone (calcaneus) moving excessively, causing the skin to get trapped between the shoe and the bone. Tight calf muscles, a bony protrusion, or biomechanical problems may all cause excessive heel bone movement, which can be addressed with stretching and orthotics.
Blister treatment has long been considered the gold standard. Taping, in my experience, does not function! Taping has little impact on decreasing shear or bone movement, and it has no effect on reducing or deflecting pressure under the foot. So, why is it still so popular? It all comes back to the distinction between blisters and abrasions that I made before. Blisters are prevented by taping, not abrasions. Rather from decreasing shear, it creates a physical barrier for the skin.
