Not all shoes are built the same but they do have one thing in common: ineffective insoles. They may add cushion and feel good when you try them on at the store, but they do nothing to promote foot health or increase performance. CURREX insoles are different. Designed by German sports scientists, they’re technologically advanced and instantly improve any shoe. They deliver more comfort and support, increase performance and reduce pressure which leads to less body fatigue and can actually help users avoid many common injuries.
