Künzli uses a lot of different boot-trees because people have different feet and because fashion asks for different shapes. That is how everyone should find his or her best shape and favourite look.
For allrounders, already the width is a help: S, M, L.
For the professional Künzli "Ortho®" and Künzli "Protect" offer the choice of E to L.
For the expert Künzli offers measuring tables, that help measure the individual foot and associate it to the appropriate size
