First Impressions

Haven't used these yet and won't until the 2021/22 ski season in Japan. I have worn the ski mid socks on other ski trips and LOVE them. These ones are well made, fit in all the right places, sit just under the knee and are very comfortable throughout. Looking forward to trying these on the slopes. I take a size 25.5 ski boot.

Not so happy

I bought these socks trying to match to similar I purchased from you a few years ago. They were also Smartwool socks. Unfortunately they are not as warm as I was hoping. I suffer from Raynauds and don’t know where to go from here to find a warm not overly thick sock.

I am a size 25.5 mondo (40 US).
I LOVE my old Smartwool Socks so much that I decided to purchase some more. I have had both the Ski Mid & Ski Light both in size medium which have been very comfortable and with no gathering or movement issues however for the past couple of years I have skied in the STM brand (recommended by a ski store) but don't like them much at all. They don't come up as high as the Smartwool and my feet have ALWAYS been particularly freezing cold and painful in the STM's so I have decided to go back to Smartwool (choosing the ski "ultra light" this time). Sadly, these feel somewhat smaller than my size M's and are quite a struggle to get over my forefoot. Once on they feel particularly tight around the top of my calves which left quite an indent after only a few minutes or so and I don't have large calves (approx 34cm under my knee)). I still love the Smartwool socks and will have to hunt around for a size XL to see if they fit better. All in all, the Smartwool socks are my top pick however personally, I would size up (in my case, two sizes). They have washed very well and have kept my feet warm.
