21 of the Best Fitness Gifts Under $25

Crew socks are becoming more and more popular this season. We like them because, if you're working out outside, the little bit of exposed ankle between the hem of your leggings and the top of your ankle socks can make you unseasonably cold. Plus, they look so cute! We like these black Alo Unisex Half-Crew Throwback Socks ($22) because they blend in with black leggings, but there are lots of different color options available.
