WEAR INSTRUCTIONS
- Apply sock to the foot requiring the use of the walker.
- Open all medical-grade hook and loop closures, and open walker lining.
- Slide the foot into the walker inner lining, ensuring that the heel is properly positioned to the back of the walker and the foot is resting comfortably on the bottom.
- Securely close the inner lining snugly around the foot and shin. Additional padding is provided to help fill loose gaps to provide a snug fit. If needed, position additional padding inside the inner liner before closing. Once the foot is properly positioned in the walker during the first application, pull up on the red tabs to permanently adhere the inner lining to the exterior plastic support shell.
- Starting at the toe area, tightly fasten the hook and loop straps on the walker. The walker should provide a snug, comfortable support without allowing the foot to slide around or the heel to lift. If there is too much movement in the walker, re-tighten straps for a snug fit.
WARNING: Always consult a medical professional when experiencing persistent pain, discomfort, or swelling. Use caution and wear only under medical supervision if you have poor circulation.
- This product has been designed and tested based on single patient usage and is not recommended for multiple patient usage.
- If skin irritations of any kind develop, consult a medical professional immediately.
- Be sure the patient performs circulation checks. If a loss of circulation is felt, or if the walker feels too tight, release contact closure straps and adjust to a comfortable level. If discomfort continues, the patient should contact their medical professional immediately.
- Extra caution and attention to patient is needed when prescribed to patients with diabetes, vascular deficiencies and neuropathies.
- Do not remove the inner foam pads which are adhered to the plastic walker.

Important Fit & Sizing Guidance
Designed for a Snug, Supportive Fit
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.
Fit Tips›
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.
Helpful Fit Tips
- This is not a standard compression sock
- Designed to feel supportive and compressive
- Fit may feel snug initially by design
- Many customers find it becomes easier to put on after several wears
- Best worn directly against the skin (not over another sock)
What to Expect›
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:
- A snug, supportive compression fit around the ankle and foot
- Targeted stabilization to help improve ankle stability during movement
- Enhanced proprioception for greater confidence with every step
- Flexible support that moves naturally without feeling restrictive
- A low-profile design that fits comfortably inside most footwear
Sizing Recommendations›
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.
Step 1
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).
