Slim Fit is not thinner material

I've used it once or twice and have initial impressions

The slim fit is not a thinner material, it is tighter around the calf for someone with a less muscular calf. I got a pair of the Lenz 5.1 heat socks and thickness is very similar to my Smartwool ski socks, I ski a LV boot and like a snug fit and these are perfect for me. If you like the thin ski socks by Smartwool and other companies than you need the Lens 6.1 heat socks. I'm really enjoying having heated socks to replace my older Hotronic heated pad for my ski boot foot bed, smaller battery packs and the BT connection to my phone makes it really easy to turn down when taking a coffee or lunch break or turn up on the chair when it's colder out than you thought. Just like the heated foot beds, don't make your toes toasty warm like in front of the fire but they don't get cold either.

I'm not sure what Lenz was thinking when they made this sock and called it "slim fit". The fit is exactly the same as the 6.1 Heat sock - the difference is in the cheaper material (more polyester/less wool). Additionally, the cheaper fabric makes the top of the sock (where the heating element strip is) more lumpy and therefore less comfortable. The Lenz heated sock is a great product - spend the extra $ for the better material in the 6.1
