AliMed Adjustable Heel Lifts allow you to add up to 3/8" of lift instantly or peel away one or two layers to create a 1/4" or 1/8" lift in just seconds. Resilient rubber layers maintain their corrective lift while still helping absorb shock at heel strike. Attractive leather top cover adds durability. These heel lifts are also a great progressive treatment for pelvic obliquity, plantar fasciitis and Achilles tendonitis. Use bilaterally to help relieve stress on the heel cord and plantar fascia. Use with a post-op shoe to eliminate pelvic obliquity. Sizing: Medium: Women's Shoe Size 9 to 12, Men's Shoe Size 6-1/2 to 8-1/2
