The Asics DS Trainer will see an update in January 2013 with its 18 iteration. Redesigns will occur in the midsole, as Asics implements its Dynamic Duomax System, enhancing stability and support with reduced weight. Also shedding weight is the seamless upper design that hugs the foot securely. The DS Trainer will also offer Asics Heel Clutching System that locks in the heel for an improved fit. A WET Grip outsole, consisting of organic and non-organic compounds, helps with traction on wet surfaces. Weighing in at 7.6 oz, look for the Asics DS Trainer January 2013 for $115.
