I know people that have used fit flops and MBTs - all similar to skechers. I do believe they work but only in the short term, its almost like you get used to walking on something different so they don't keep working. My friend has done well with the fit flops in that she wore them over the summer months last year and seems to tone up a bit, because then had a break from them and went in to them again around may time they have helped tone again we feel . I cannot advise though that they won't do any harm to you in your condition.
