A fresh idea from UK hosiery champs Pretty Polly, now you can keep your feet smelling sweet with these innovative, odour controlling Pretty Polly Sweet Steps 60 Denier Opaque Knee Highs. The Sweet Steps range uses patented Odegon technology, a system exclusive to Pretty Polly. A lightweight patch fused to the sole of the knee highs effectively traps odour molecules as they pass through the nano-porous material, significantly reducing foot odour. The Sweet Steps heart-shaped patched last for the lifetime of the knee highs, and is totally skin safe, and kind to the environment.
