During 2009 Asics produced for sale the GT-2140 and—if not creatively, at least predictably—for 2010 we now have the 2150.

This shoe changed between last year and this, just as this company’s Kayano underwent an overhaul. Like the Kayano, this model is more stable than the GT-2140. What we wrote about the Kayano holds true for this shoe’s update as well.

It’s not better or worse, just slightly more stable and you’ll like that—or not—based on your footfall and foot structure. There is no change in the amount of cushioning, as judged by those of us who wore the shoe during run trials. This should be no surprise since there is almost no difference in the placing of the Gel units. The more robust support seems to come from a more supportive forefoot on the medial side of the shoe. It appears to us that Asics uses the same injected SoLyte process in the midsole of the new GT-2150 as used in the Kayano. It is at certain points just slightly less soft then in the GT-2140 so, when you tend to pronate during the push off phase, it offers better support and limits the amount of pronation. This model will be a big hit for Asics in 2010.
