I am a huge fan of skechers and since they started shape-ups and tone-ups I wear nothing else. For those familiar with the technology, these feel very different, much more spongy and the instability pods do cause instability, they are lovely and soft and comfy inside though. For those not familiar it all started with MBTs which is based on the way a barefoot Masai tribe walk, heel to toe rolling your sole. MBTs are to be honest a bit ugly, skechers are not! Size wise although they are a less bulky style running trainer, they are very roomy inside especially around the toe so no rubbing, I'm a 6 and its a lovely fit. I got the white and pink pair, the pictures don't really do it justice, I was a bit dubious how they would look (got them on a lightening deal so wasn't looking for them specifically), but was delighted when I opened the box. As with all skechers trainers they come with 2 pairs of laces, these being white and a dark pink similar to the colour above the sole.They are supposed to tone buttocks thighs etc due to the new way you have to walk the design of the shoe is literally forcing your body and muscles to re-balance themselves, you may loose a couple of lbs if you are unfit, but don't expect miracles. The reason I get these now is also because they are so comfy, ever walked round a theme park all day in trainers and your feet and legs feel dead by the end of it? not with shape-ups or tone-ups, you can walk for hours and hours. My mum has knee problems so I have bought her a pair for xmas. Its a revolution in shoe wearing, I wish they had been made when my job involved walking on a hard floor all day!
