3mm AEROSPRING™ FOAM under the forefoot & specific for tight-fitting footwear
The Superfeet FLEX series of insoles offer an excellent introduction to the Superfeet experience. The flexible heel cradle and active Aerospring™ full-length foam combine to create a contoured shape under the foot. The specialised FLEX design allows the insole to easily conform to the widest range of footwear.
HOW IT WORKS:
Superfeet FLEX insoles adapt the generic, 2-dimensional surface inside your shoes to your 3-dimensional foot. The distinct Superfeet shape helps to stabilise the foot, while the flexible heel cradle and foam provide support and comfort with every step. No break-in period needed.
