Right 4mm(1/8") Limb Leg Length Discrepancies Corrective Heel Inserts Insoles with Shoe Fillers for Uneven Hips (1 Left + 2 Layer lift)

I like that these extend a bit further than just the heel. It helps keep them in place.

Too bad dont buy

Helped with my knock knees. I walk much better when these are in my shoes. Love them! My husband uses one pair for his bowed legs. Great product!
