Difference Between Asics 2120 and 1120

Choosing the proper running shoe can be confusing. Most companies have multiple models, and many of these models appear to have little or no difference between them. There are, however, a number of things a runner can compare prior to selecting a shoe. On the surface, the Asics 2120 and Asics 1120 may seem similar, but a closer examination reveals several significant differences.

  1. Category of Shoe

    • Most running shoes are built for a particular type of runner based on gait, body size and the way the foot lands. Both of these models are stability shoes, meaning they have minor motion control features. Neither is as soft as a "cushioned" shoe or as corrective as a "motion control" shoe. The 2120 is a slightly beefier neutral shoe and the 1120 is a lighter and more cushioned model with a few more anti-pronation features.

    Technology

    • Due to a stiff midfoot bridge -- a rigid plate that runs from the front to the back of the shoe -- the 2120 has a firmer midsole, although there are softer areas under the toes and heels. It has a wide heel, also to improve stability. The 1120 is a softer shoe thanks in part to a foam layer beneath the sockliner. It also has a stiffer, but lighter, midfoot bridge and a strategic mesh panel on the upper to improve fit.

    Uses

    • The 2120 is sturdy enough for heavy runners who run with a neutral gait. This typically means the runner has normal arches and no major biomechanical issues. It should also work for lighter runners who overpronate a bit. The 1120, while lighter and more cushioned, is the more stable shoe, so it is more suitable for average sized runners who need more pronation control in a lighter shoe.

    Other Pertinent Points

    • Two other points are usually of interest to prospective purchasers. The first is weight. The 2120 is the heavier shoe, weighing in at 12.0 ounces for a men's size 9. The 1120 weighs 10.0 ounces for the same size. The second point concerns price. Both the 2120 and the 1120 originally retailed for $95.00, so a choice between these two shoes truly comes down to which model fits the runner's needs better.
