Feet rarely complain when asked to hike for miles in 6-inch stilettos or fill in at piano competitions when hands go on strike. Coddle overworked human hooves with today's Groupon: for $22, you get a spa pedicure at Leah Nickie Advanced Aesthetics in Boulder (a $45 value).

Kim Huggins, the talented nail technician at Leah Nickie Advanced Aesthetics, channels a quarter of a century of experience into each perfectly polished pedicure. The 75-minute pedicure ($45 value) pampers paws with all-natural lotions, salves, and nontoxic nail polish. The spa safari begins with a foot soak in a warm, aromatic bath of Dead Sea salt crystals that calm the nervous system, combat fluid retention, increase circulation, and strengthen nails, enabling pinkie toes to lift pregnant elephants with ease. After tweezing away overgrown cuticles, a toe farm technician clips and shapes nails, then exfoliates expired skin from the base of human pedestals. Ankles, calves, and feet receive a soothing massage to melt away stress and toes get a new paint job with formaldehyde-free Zoya nail polish, available in a jellybean jar of colors.

Leah Nickie Advanced Aesthetics' eco-chic décor creates a comfortable, welcoming environment, and the free WiFi allows beauty addicts to shop for opened-toe rain boots or schedule their next treatment during their appointment. Additionally, Groupon customers can buy a $50 gift card for future nail services for only $40; this card is non-transferable and must be purchased on the day of your Groupon appointment.
