Difference Between Asics 2140 & 2150

The Asics 2100-series are running shoes intended for middle-to-high-distance runners. The shoes are constructed for normal arched runners that require moderate pronation stability. According to Asics, the series provides the perfect blend of support, comfort and cushion for runners.
  1. Heel

    • Gel Cushioning is a two-part construction in the heel of the Asics 2100-series shoe that provides shock absorption to the heel and stabilizes the transition to the mid foot. In the GT-2150, the system is longer and extends higher up on the medial sidewall, which provides more stability for the mid foot transition. On the outer part of the shoe, the shape of the heel cage is more scooped out on the GT-2150, to lessen ankle irritation.

    Forefoot

    • The sole on the forefoot part of the shoe is more flexible on the GT-2150 when compared to the GT-2140. The GT-2150 is more flexible to enable a better lateral release while running. It also has larger pods to provide additional stability, particularly during the heel-strike to toe-off transition.

    Upper

    • The upper on the GT-2150 has been modified to include a Comfordry sock liner that is made of memory foam and is seamless, to enhance the comfort. The liner of the shoe is made from a material with anti-microbial properties that also helps keep the foot dry.

    Weight

    • Another important upgrade for the GT-2150 is that it is lighter than the GT-2140. The men's GT-2150 weighs 11.6 ounces, while the women's weighs 9.5 ounces, both of which are approximately 0.5 ounces lighter than the GT-2140 model. The difference in weight is mostly due to a change to the midsole material, which was switched from Eva and Speva foam in the GT-2140 to a Solyte foam in the GT-2150.
