Sizing and product information

For knee high socks and calf sleeves, your sock size is based primarily on your calf circumference around its widest point. Your shoe size is a secondary reference point. If you are in between sizes, we recommend you size up unless you want a tighter fit. For all below-the-calf socks, your shoe size is the primary determinant of size. For your convenience, all of our products have a sizing chart on their respective pages. If you have any doubts, please send us an email and we'll help you select the right size.

Compression socks are tight and can be difficult to put on if you try to put them like a normal sock. Here’s an article and video that shows you the best and easiest way to put on your compression socks.

We recommend the knee high socks for the maximum benefits of compression. These socks are excellent for anyone who suffers from shin splints, cramping, swelling, Achilles issues, or plantar fasciitis. They're also great for runners looking to rehab their leg after a long run or workout. Our Signature Crew socks are the perfect way to give your feet and ankles a cuddly hug! They provide firm pressure from the ankle to the mid calf, giving your feet the support they need during exercise, travel, and long workdays. Our innovative ankle socks are made for the runner in you! The cushion underfoot absorb a maximum of shocks and vibration from the ground to reduce aches, and the breathable top keeps your feet cool during an extended bout of muggy 90-plus degree days.

No, none of our products contain latex.


Wash on cold cycle with like colors. Do not use bleach or fabric softener. Air dry or hang dry to maintain the elasticity of the compression. Here is a short instructional video on how to best care for your Blitzu Compression socks and sleeves.

Our socks and sleeves are made of premium flexible synthetic fabrics that don’t shrink. We encourage you to avoid warm or hot water and the use of a dryer as these methods may degrade the compressive quality of the garment.
