Too cold at the toes for a winter sock
- Ronnie 23 October 2025
The fit, length and colour are all top notch. The upper part of the sock is also reasonably warm but at the toes, it is very thin which means you still get cold toes. Conducive to selling the Toe Thingy 2 from the same brand. But not good as a winter sock!
Pros & Cons
Beautiful white
Comfortable fit
