We always recommend to hand wash with mild soap and hang dry. That said we do have many customers that throw Hot Sockee into the washer and tumble dry on low setting with no issues.

When we created the Hot Sockee we tested many different thickness up to 4mm. We found that the Higher Quality Neoprene in a 1.5mm thickness offered excellent heat retention while offering best fit in a wide variety of shoes and boots.

3mm is just too thick and made our test fitters shoes and boots fit too snuggly which resulted in poor heat retention.

We recommend Hot Sockee be worn over socks.

We do have many customers that prefer to wear under socks or no socks depending on the environment. Usually no socks is used in your home while wearing slippers, while over socks is best for cold temperatures outdoors.

Since Hot Sockee is a half sock the entire length is not as important as the width. This is why our shoe sizing chart is only a recommendation.

The number one reason for this is a tight fit.

Either Hot Sockee itself is too tight, or the combination of Hot Sockee with your sock is overly snug in your shoe. Try to open your laces or buckles up a bit to adjust.

Try different sock combination.

If the Hot Sockee is too tight we offer a 100% money back guarantee just for this reason, we want to be sure everyone that makes the purchase gets the correct size.

Feet can be tricky and there are many variables. If you are unable to benefit from the Hot Sockee we get it! Please utilize our money back guarantee.
