Adjustable Heel Elevation Wedge

Measures 30 cm long × 15 cm wide × 5–10 cm high (adjustable via 3-step incline); weighs 0.8 kg; built from dense, non-compressible material with uniform density throughout — no soft spots or deformation under pressure. Surface finish is matte-textured for reliable traction with bare skin, socks, or minimalist footwear. Bottom surface pattern matches floor contours to prevent rocking on uneven surfaces. Designed for repeated use across fitness, flexibility, and recovery contexts without wear-related performance loss. Functionally calibrated to increase ankle dorsiflexion range by up to 15° at 10 cm elevation — enabling deeper squat depth while preserving lumbar neutrality and reducing anterior knee strain. Enhances stretch intensity in standing calf stretches by increasing lever arm length without requiring forward trunk lean. Also supports weight-bearing balance drills for ankle stability retraining. Common integrations include: integrating into warm-up circuits before Olympic lifting sessions; adding to yoga flows for modified poses requiring forefoot lift; using post-run for seated or standing soleus-focused holds; and incorporating into post-operative rehab plans (e.g., 6-week post-cast mobility phase) under clinician guidance.
