Gym and Studio Rentals Can Be Gross — Here's When to Buy

To be honest, we were a tad shocked when we realized that rental grip socks were an option at some locations. Grip socks are a requirement at some studios, and most boutiques will have you bring your own or buy a pair, if they're strict with the sock rule. While it might seem like you're saving money by renting, think of what you're compromising here. Grip socks are $10. How much is your health worth?

Our suggestion: That's gross, man. Get your own.
