I first heard about mbt m walk from a friend who had got them from her pilates teacher. She couldn’t recommend them highly, so after a bit of research on the web I became sufficiently intrigued to try and track some down.
While most vendors appear to be individual pilates or fitness practicioners, I also found a shop in York (Sarah Coggles – a very trendy clothes shop – I didn’t fit in at all). There, on an overcast Saturday morning, I found a few pairs of some ugly-looking mbt m.walk with very strange, convex soles.
