What would you choose? I need to lose a stone and a half (DD2 is 11 weeks old and I have serious work to do). I don't want to run due to a bad back so need something I can walk fast in that ideally supports me and doesnt make my back worse. My posture is awful so the MBT type things appeal but there again trainers may be more versatile.
Oh and MBTs are in administration so I can only buy online which I didnt want to do. Trainers I can get fitted but the ones I just tried were £100!
