Asics GT-2160

The GT-2160 was released in spring 2011 as a refresh to the GT-2000 line. It was the update to the GT-2150, released in November 2009 in specialty stores with a wider release in January 2010.^[2][3] The shoe only lasted a couple of months on the market before being replaced in January 2012 by the GT-2170.^[4][5][6]

Updates to the shoe featured a softer lining inside for better comfort. The shoe features softened Gel and foam in the midsole for a softer feel and added deep grooves in the outsole. The shoe was the lightest model up to that point and also lighter than the current Gel-Kayano model at that time.^[7] Stability in the shoe is provided by two units of Asics Gel that are found in the heel and forefoot and the DuoMax system, which is a hard piece of foam found in the mold of the midsole. The main addition to the GT-2160 was the Guidance Line, a longitudinal groove carved into the midsole that guides the foot through the most efficient stride while also reducing weight.^[8]

The shoe was brought back in July 2023 after the popularity of 2000s running shoes in the early 2020s.^[9] The release was first introduced with Montreal based fashion brand, Dime, and then followed with a general release.^[10][11][12]
