I had purchased the previous version of this product (thicker, lime green gel on the bottom) and LOVED them. I finally wore through those and had to buy replacements. I saw via Amazon that the gel sole was now blue, and assumed only the color had changed. EVERYTHING has changed about this product -- the blue gel is a lot less firm, and as another reviewer said, it really does feel like you're balancing on a melting gummy bear. The gel layer is much thinner, as is the top fabric layer, and within the first 24 hours of wear the two layers were separating and sticking to my feet and my shoes. Very disappointed, and I won't be buying this brand again.
