The lack of the more durable midsole material or stability elements of previous GT 2000 models is very evident. These shoes warmed up very quickly, in less than 2 months, giving almost no stability. Although they fit better in the toe area than the 9 version, Asics have gone to great lengths to make them soft and plush. This shoe needs a firmer midsole. Unfortunately, the current model doesn't offer the stability that all the advertising hype claims.
