Injinji Performance Toe SocksApparently, some socks can be good for your feet - like these Performance Toe Socks from Injinji. The Anatomical Interface System is designed to separate the toes with a thin, anti-friction membrane that is lightweight and breathable. Seamless construction allows for a more natural restriction free movement from your heel to your toes, encouraging healthy circulation, and eliminates skin on skin contact between your toes to prevent heat and moisture build up and blisters. So when you step out of your challenging stilettos, consider stepping into these socks. $42 from Zappos.com.
