Feet produce a lot of sweat, but the smell does not come from sweat itself. Odour develops when skin bacteria break down sweat in the warm, moist environment created inside closed footwear. This product is made for that situation: it helps reduce bacterial growth on the skin surface and covers odour with a light perfume composition.
The spray format is also practical for feet because it can be applied across the sole, around the toes and between the toes without touching the skin with your hands. These areas are harder to reach evenly with a stick deodorant and are often where moisture builds up most. The product dries quickly and is described as not leaving a sticky layer, which matters when you need to put socks or shoes on afterwards.
A regular body deodorant may not be suitable for shoes and may be awkward to apply between toes or to the sole. Vitawohl can be used both on feet and on the inside of footwear, so it addresses odour where it commonly develops during long days in closed, rubber, sports or work shoes.
