"I bought gel nimbus 18 shoe as a surprise birthday gift for my husband. My husband loved the color (grey/ teal/ yellow) as he opened the gift. He was excited to wear it. He liked the feel of the shoes. Great cushioning. Excellent for running, walking , etc. I did couple of research before doing this purchase. This shoe proved that it is good for neutral and supination. Not for pronation. This is my husband's first expensive running shoe . I think it will pay off in the years to come (no need to buy shoe every 2 yrs beause of wear off etc). The size is true to fit. In one word a PERFECT shoe . I hope this review helps the other buyers."
