2. Sizing and Fit
To ensure the best fit and optimal support, follow these sizing instructions:
- Measure: Measure the circumference of your leg 2 inches (approximately 5 cm) below the center of your kneecap.
- Consult Size Chart: Refer to the official Shock Doctor sizing chart (typically found on product packaging or the manufacturer's website) to find your corresponding size.
- Between Sizes: If your measurement falls between two sizes, it is recommended to select the larger size for optimal comfort and to prevent over-compression.
