Ghost 7 sneaker by Brooks. Brooks is well known for the quality of their sneakers. Synthetic mesh upper, synthetic textile lining, proprietary foam midsole, rubber outsole. Worn a few times. I can offer to ship with Adidas or Brooks Addiction 13 insoles as replacement. NOTE: Original size is 9, but I marked as 8.5 here because it runs small. They are snug and I am usually an 8.5.
