Shoe size is provided as a general guide. For the most accurate fit, we recommend measuring your foot circumference and referring to the measurement chart before selecting your size.
See Size ChartThe PowerStep® Dynamic Ankle Support Sock (DASS) combines the stability of an ankle brace with the flexibility of a compression sock, helping you stay active, and get back to the activities you love without the bulk of traditional supports.
Whether you’re recovering from a sprained ankle, dealing with chronic ankle instability, returning to sports, or looking for extra support during long days on your feet, the DASS is designed to help you move with confidence and stay active doing the things you love.
Its low-profile design fits comfortably inside most athletic and casual shoes, making it easy to wear during workouts, walking, work, travel, or daily activity.
Designed for movement, recovery, and everyday wear, the DASS delivers targeted compression and adjustable ankle stabilization to improve confidence and support long-term mobility.
The Dynamic Ankle Support Sock is designed for active individuals looking for comfortable support during movement and recovery, including:
*Once you've completed your medical professional's recommended treatment plan.
The Dynamic Ankle Support Sock is intentionally designed with firm compression to provide stabilizing support. Because of this, it may feel tighter than a traditional sock or sleeve during your first few wears.
If you are between sizes, have wide feet, a high instep, swelling, or prefer an easier on/off experience, we strongly recommend sizing up for the best fit.
Getting the most out of your Dynamic Ankle Support Sock starts with the right fit. Keep these tips in mind for the best comfort, support, and overall experience.
The secure, performance-focused fit helps provide targeted compression and ankle stabilization while allowing natural movement during activity and recovery.
When wearing the DASS, you can expect:
For the best fit, refer to the measurement and shoe size chart before purchasing.
If you are between sizes, have wide feet, a high instep, or experience ankle swelling, consider sizing up for easier application and improved comfort.
The DASS may feel snug during the first few wears, which is normal and expected as part of its supportive design.
Measure around your foot by wrapping a flexible measuring tape under your heel and over the highest point of your instep (top of your foot).
Match your foot circumference to the size chart below to find your recommended DASS size. Shoe sizes are included as a secondary reference only.
