The Brooks Ghost 15, also known as the successor to the Ghost 14, is a great running shoe for neutral runners. The difference between these two models is that the Ghost 15 has an even tighter fit around the foot and the midsole is made of DNA LOFT v2. This allows for a softer push-off and a softer landing. Despite these differences, many runners find the Brooks Ghost 15 to feel just as comfortable as ever during wear.
