MEASUREMENT INSTRUCTIONS/
➤Use a soft tape measure and with a straight leg, measure the circumference of the knee joint, thickest part of the calf, and bottom of the quad about 2-3 inches above top of knee.
➤ Use the knee joint measurement as the primary reference to compare to the size cart. Use the calf and quad measurements as a secondary reference the size chart. Size chart is an approximate recommendation. Fit of the sleeve will vary based on the preference and leg shape of each individual. If you are between sizes, we recommend sizing up.
➤ These sleeves are made to be extremely tight and rigid, they can be extremely hard to get on and off. Loss of feeling in calves and toes is a common occurrence.
➤ We are NOT responsible if you cannot get them off and cut the sleeves.
*We offer a one year warranty from date of purchase for defects, damages or tears. Please note: We are not responsible if you cut the sleeves off.
