The 1st time I bought these I was very excited because of what they promised. I bought 2 pair. Got them and they were both falling apart within a few months of use. However, they did seem to help my feet problems so I went ahead and bought 3 more pairs (3 only because they were discontinuing nearly all the double-wide options at the time). Same crap quality with them falling apart Very quickly. I've had other brands which have lasted me for YEARS. NONE of these lasted more than 6 months. And quite frankly, with my super expensive molded prescription shoe inserts, they don't do me any better than with other brands without the so-called trampoline springs. DEFINITELY not worth the money or the hype.
