Great for wearing with boots
Bought for my daughter living in London where it is currently wet and extremely cold. She was not familiar with the company. SHe wears the Ultra Lite thickness with boots. Loves them.

These are so soft and I wore them to a to a football game with the temps in the high 30’s and my feet didn’t get cold. I wore shoes similar to uggs

I bought these for my daughter, whose feet are always cold, no matter the weather. However, she hates bulky rag wool socks (my idea). She loves the ‘Heat Holders” because, they’re super warm without being bulky. Shes up in Albany, NY where the weather is frigid all Winter long.
