They feel like a sheep is hugging your feet

Honestly, I only wore these around the house, because they’re thicker than any sock I wear (would need to be hiking in snow for an extended period to wear these – my feet run warm). So I can’t comment on outdoor functionality, but based on the Fusion Light I have no doubt they’d be great. From indoor use, they feel beautiful – the knit is far softer and more comfortable than any sock I’ve ever worn (they feel like a sheep is hugging your feet), yet they’re surprisingly durable to pulling (snags on wooden floorboards). I basically didn’t wear shoes indoors all winter because these were on my feet. Sorry that I didn’t have an opportunity to test them in the outdoors where they belong.
