Preventive effects of various types of footwear and cleaning methods on dermatophyte adhesion. J Dermatol. 2006 Aug;33(8):528-36
Tinea pedis is contagious and typically spreads from infected to non-infected persons. The purpose of this study was to evaluate the efficacy of footwear in preventing tinea pedis adhesion. Using the stamp culture method, we investigated the effectiveness of preventing dermatophyte passage by the wearing of stockings made of nylon, socks made of cotton and tabi (Japanese socks), as well as the effect of removing dermatophytes from these items by washing with soap, cold water and cold water after turning inside-out. For sandals, sneakers and boots, we also investigated the effect of dermatophyte removal by pouring cold water into the footwear, wiping with a wet towel, and pouring boiling water into the footwear. The wearing of socks or tabi was effective in preventing passage of dermatophytes. The stocking material proved to be too thin to prevent passage. On the inner side of socks (the side of the sole), all treatments were effective at removing dermatophytes, but on the outer side of socks (the side touching the surface of the sandals), the treatment of washing in cold water after turning inside-out resulted in significantly more dermatophytes as compared with the other treatments. Pouring cold water, wiping with a wet towel and pouring boiling water were all effective for removing dermatophytes from sandals and sneakers. However, for boots, the treatment of pouring cold water was less effective. To prevent the adhesion of dermatophytes to sandals, wearing socks or tabi was effective, and the treatments of washing socks in cold water after turning inside-out and of pouring cold water into the boots were less effective than the others.
