Build your sustainable pack

The most sustainable sock is the one you don't replace.

Bulg Nr.788 starts with combed-cotton yarn spun with wind energy, then adds a 200-needle knit and a terry-cushioned sole built to outlast the throwaway pair, so a sock you keep longer is its own kind of sustainability.

“Honestly didn’t expect to like these as much as I do. So soft, and the compression is just right, supportive without feeling tight. They fit like a glove, kinda wrap around your foot perfectly. Colors look great too, even better in person. Already thinking about ordering more.”

“They are good for summer usage. My only suggestion is to watch the size you order. The default is small. It was my fault and my wife’s gain.”
