Pedestal Footwear Makers Michael Lyon and Brendan McKee noticed folks like them at the gym working out in socks and carrying around their sneakers. It might sound strange, but by ditching shoes when you’re lifting weights or doing yoga or barre, you can give feet the opportunity to get stronger, which can help other aspects of health, like posture and balance.

The duo decided they could make something better suited to the indoor training job. Their socks have super-grippy soles that lend stability, but don’t sacrifice foot freedom.

They’re made with silver thread throughout to help control moisture and bacteria (and the resulting odor), and abrasion-resistant thread in high impact zones like the heels.

Not only can you help strengthen your feet by pulling on these socks before you work out, you can feel an overall better connection to training, too.
