Getting the right shoes was my first concern. Making sure that my foot gets the perfect mattress to rest and roll my second. René recommended Switzerland's first address for ambitious runners and sports professionals: NUMO Systems in Dietikon, Zurich. Based on a clinical testing routine the NUMO team defined the target arch support and shaped it 3D. After a few weeks the inflammation of my right achilles' heel disappeared. And that's how my high-rech rubber looks after approx. 1000 km of training.
