Peppelt

Invisible Heel Socks

Love your slingbacks but hate the slip, sweat, and blisters? Meet the Peppelt Invisible Liners—the first sock designed specifically for open-back heels, mules, and flats.

We’ve replaced the bulky heel of traditional socks with a crystal-clear, ultra-stretch strap. It creates a secure, non-slip fit that disappears against your skin, letting your shoes take center stage while your feet stay cool and dry.

Frequently Asked Questions

Will the strap snap easily?

Not at all. We use a high-tensile, industrial-grade nylon designed specifically for elasticity. It stretches up to 2x its length to accommodate your foot movement without snapping or losing its shape.

Does the strap dig into the heel?

No. The strap is designed to be flat and soft against the skin, not round like a rubber band. This distributes pressure evenly so you won't feel it digging in or causing friction burns, even after a full day of walking.

Does the size of the sock feat me?

These liners are designed as "One Size Fits Most." The cotton toe box molds to the shape of your foot, and the silicone heel strap provides the adjustability. They fit comfortably for US Women's shoe sizes 5 through 9.5.

Can I see them while wearing shoes?

That's the best part—they are virtually invisible. The toe cover is cut low ("deep mouth" design) to hide inside pumps and mules, and the transparent heel strap blends seamlessly with your skin tone, making them look invisible in slingbacks.

The "Barefoot" Look, Upgraded.

We love the look of slingbacks and mules, but we hate the blisters that come with them. Our design features a crystal-clear heel strap that blends seamlessly with your skin tone. It’s the perfect way to protect your feet while keeping your outfit 100% on point. No one will know you're wearing them but you.

Say Goodbye to Foot Fatigue.

High heels put serious pressure on your feet — especially the ball and heel.

That’s why Peppelt’s invisible sock is designed to reduce friction, prevent slipping, and shield your skin from painful rubbing.

You’ll walk more comfortably, with less strain and no blisters — even after hours on your feet.

Smart-Stretch Technology.

Cheap liners slip off after a few steps. Ours are engineered with high-tensile silicone that stretches to fit your unique foot shape without snapping. The flat-lay design ensures the strap grips your heel securely without digging into your skin or cutting off circulation.

The "Barefoot" Look, Upgraded.

No slipping. No sweating. No blisters. Just the invisible confidence to walk from your morning commute to your evening dinner without a single adjustment.

They are very comfortable!! I thought they would be too big for me, but they aren't; I wear size 35.
