Traceless, the female-founded, biocircular start-up, has teamed up with European fashion retailer C&A to create a replacement for single-use plastic sock hooks - those seemingly inconsequential plastic display hooks that allow retailers to hang socks on a wall. Using Traceless' home compostable material of the same name, C&A's pilot project is the first step in a long line of much-needed retail material swaps, but we can't help but wonder if simply displaying socks in a different way could do away with this need altogether.
