Lemon-scented socks help freshen up foot fetishes

Foot fetishists sometimes get the smelly end of the stick when it comes to the personal hygiene of their significant others. Thankfully, a new fashion "technology" aims to help the issue. A chemically-engineered lemon-fragrance microcapsule is able to be stitched into items such as socks and undergarments to provide a citrus-y scent all over. The engineers were able to use polyurethane-urea in place of the toxic formaldehyde found in scratch-n-sniff stickers.
