When we build the next model in the 2000 series it must ride like its predecessor. This is so important and ensures the consumer gets that no fuss brilliant performance 2000 wearers have come to expect. The GT-2150 delivers great stability for slight to moderate over-pronation issues. The ride is incredible with a super responsive midsole while the sponge rubber AHAR forefoot delivers great durability but also provides a super feel under foot.
