These are the most uncomfortable shoes I've ever bought. I just can't walk with this pair. My legs hurt. I have 2 pairs of zoom turbo 2 and they are so comfortable they walk on both the top and bottom of the sole and i don't get tired at all but this peg 37 is too sticky the sole is hard the Pressure from above hurts my legs so much. Today was the third time I tried to get through, but it still hurts and I can't walk at all.
