Bought the original ZigKick's, but had to take them back because the 8 was too big. They did not have them in 7.5, so I bought the ZigKick Ride's in 7.5. They are great! I LOVE THEM! I did not know they had all of these designs, or else I wouldn't have bought the blue and green color. They are so comfortable and really enhance my workout. I wear them to run, Body Step, Body Combat, everything. I will never buy anything else- as long as it is in the zig tech family!
