After a long day of skiing on the slopes boots inevitably get wet. This is no surprise when you stop to consider that feet contain 250,000 sweat glands, which translates to one cup of sweat every day. Skiers are faced with the 'wet boot problem' after just a few runs, and it is just plain uncomfortable wearing sweat drenched boots the following day. Sweat inside your ski boot also makes for a perfect environment for microbes. The ski boot is a working model for the breeding of harmful bacteria, enabling it to multiply at blazing speeds. Though we may not be able to visibly see this natural phenomenon, the smell is often hard to disregard.
