Xtenex (indeXed-TENsioning-nEXus) is a worldwide patented elastic lace technology that produces adjustable tensioning between shoe eyelets. 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:
1) 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.
2) 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.
All laces are supplied in pairs
