I had a 1-and-a-half hour session alternating between the Speedgrips and the Zero Glide ones and I wasn't that impressed. They were a little bit thicker and padded, so yeah they are a little bit more comfortable. The non-slip feature seems to improve as your feet sweat, but initially they are less non-slip than the sticky Zero Glide. Overall I think looking elsewhere would be better. I might get the currexSole next.
