Frequently Asked Questions.

It’s the Double Layer® that creates the Anti-Blister System™. The Double Layer® is designed to place the foot in the best possible environment to avoid hot spots and blisters. Blisters and hot spots are caused by three factors: excessive friction, excessive moisture and excessive heat. The interaction of the two layers absorbs the friction normally passed onto the outer layers of the skin. The inner layer fabric wicks away the moisture from the foot. This quick moisture removal eliminates the heat buildup. The Double Layer® absorbs the friction, wicks the moisture and keeps feet dry so blisters never form.

If you experience blisters or are not 100% satisfied with the performance of our product, simply return the socks with the original sales receipt and proof of purchase for your money back or a sock replacement of another style. Send returns to: Wrightenberry Mills, Inc., 910 Cleveland Avenue, Burlington, NC 27217.

You can purchase our Double Layer® socks on this site, on Amazon, or at specialty outdoor retailers across the US and internationally. Looking for a specific store or location? Take a look at our Store Locator at the bottom of our website.

You can machine wash your socks inside out in warm water with a non-bleach detergent. Do not use bleach or a liquid fabric softener. Tumble dry with no heat. However, because of the quick wicking fabric, you always have the option of air drying your socks instead. Too much heat in the laundering process will cause the fibers to shrink.

Here is a size chart that uses your shoe size.

Our crew length socks generally come to the bottom of your calf muscle. Our quarter length style will rest just above the ankle bone. Our lo quarter length socks will rest just on or below the ankle bone. Our tab style is the lowest cut and generally sits just above the top of a running shoe profile. It features an extended heel tab to avoid Achilles rub.

All socks will slip down in your shoes if the sock is too small for your foot. To help ensure you have the right size, a YHeel gore can be found in the heel pocket of each sock. This YHeel gore must be positioned to point to the back corner of the heel. If the YHeel gore is pointing under the heel, the socks are too short, and the result will be socks that slip down into your shoes.

Of course, it is impossible to know the exact life span of socks. However, we do recommend replacing your socks every time you replace your running shoes. Running shoes last approximately 300-500 miles. Light hiking cushioned socks should be replaced every new season.
