If you don't wear proper footwear and underwear that lets your skin sweat, your feet are likely to collect moisture and smell bad at the end of the day. If you still play by the rules, your feet still smell bad, watch out:
Marthand antiperspirant powders are ideal for feet that suffer excessive sweating, as they capture moisture and do not allow more to be generated. In this way, the feet are dry, hydrated and odourless at the same time.
Keep your feet free of moisture and bad smells!
