They were actually quite comfortable, the insole was even extremely comfortable, although it was only made of foam.

However, with the black model I had, the orange lining rubbed off on the socks at first... and the M-Budget color choice was just awful.

A new edition with different color variations could be interesting. Perhaps also a design survey where you can color a sneaker (similar to Vans, MES Footwork, Nike, Converse etc.) and then everyone can choose which two to three color variants are produced.
