Like gasoline, feet must be carefully treated and refined before they can be used to propel automobiles. Amplify your octane with today's Groupon: for $22, you get a mani-pedi at Studio J Salon in Affton (a $45 value).

Studio J Salon’s highly experienced staff brings more than three decades of prettifying prowess to its cornucopia of beauty-boosting services. Nail specialists treat fingers and toes to a revitalizing scrub of sea salt and bestow upon them a comprehensive clipping, buffing, filing, and painting, readying them for stylish high-fives and the eventual comeback of fingerless gloves. Agitated stompers submit themselves to the soothing touch of refreshing creams and a hot towel, and a fortifying paraffin wax can ably open up pores and soften skin (a $5 upgrade, not included in today’s Groupon). Earthy, homespun environs ensconce guests during the 90-minute treatment, and an onsite massage chair gaily rattles away stress, anxiety, and tacky candy necklaces.
