Some people keep a gratitude journal. Pilates girls keep a mental list of every instructor who's ever said, "It doesn't get easier... you just get stronger." Congratulations. That's your Burn Book now.

The Formé by Mercedes Pilates Burn Book Grip Sock is for the women who know boutique fitness is equal parts therapy, torture, and personality trait. Featuring a playful nod to the workouts we love to complain about (and immediately sign up for again), these socks are designed with sticky grip soles to keep you confidently planted through Pilates, barre, yoga, and Lagree. Because the only thing getting roasted during class should be your glutes.

Soft, supportive, and built to move with you, they're ready for every plank, pulse, bridge, and "last set" that somehow turns into three more. Whether you're silently judging the instructor for adding another spring or mentally drafting your post-class group text, these socks understand the assignment.

Because if we're being honest... the reformer has been personally victimizing all of us.

Iconic attitude on top. Tiny rubber miracle workers underneath.
