Supportive Apparel sizing is determined by height and weight which helps us predict both the fit of the garment and the cable support system. By using height and weight, we can accurately determine the length and position of the cable support system which is not possible with traditional athletic apparel sizing.
Find your size with our size picker or by looking at our size chart. You can find the size picker above where it says "Find Your Size" next to the size selections. If you find yourself on the border of sizes, we recommend sizing up.

Still Have Questions?
Stoko accepts returns & exchanges within 60 days of the purchase date.
We encourage you to put your Supportive Apparel to the test before deciding to return. Move in them, get sweaty, and give them all you got. There is a short break-in period with your Supportive Tights. This means it will take a bit of time before your tights begin to regulate and feel comfortable on your body. They can be a total pain at first and challenging to get used to, Supportive Apparel is very different than any other tights or braces you’ve tried.

All-Purpose: Both the Supportive Tight and K1 Flux are engineered to deliver support in a variety of activities and is our most recommended product for all-around use. From everyday activity to court sports to golf, the K1 Flux and Supportive Tight can do it all while also keeping you cool with knitted ventilation.
Ski & Snow: K1 Summit is engineered to deliver support and warmth. It was designed for snow sports, such as skiing, snowboarding, and cross-country skiing.
Run & Hike: K1 Tempo is engineered to deliver support and keep you cool in warm environments, such as: running, hiking, and training.
Similar to other traditional/medical grade knee braces, the Supportive Tight provides support and stability to the body in compromised knee positions; however, the Supportive Tight achieves these outcomes through different means. The Supportive Tight relies on tension throughout the Stoko Support System to generate support, which is made up of cables that are integrated into the tights. The result is support that moves with your body and doesn’t compromise on comfort, aesthetics, or support.
