This technology addresses the source of footwear related pain and discomfort: lace migration. Lace migration is the gradual movement of the shoe lace toward the forward bend of a shoe, which causes two main problems:
- Binding; a tightening and restricting pressure at the top of the shoe. This can lead to foot fatigue, pain, numbness and restriction of natural foot swelling.
- It loosens the fit around the footwear’s metatarsal area, which causes increased slipping and reduction of forward foot stabilization. This can produce heat friction, which often leads to painful blisters.
