Altra Superior 4.5 Men
Big G Says…
The Quantic mid-sole cushioning is noticeably firmer now. While improving the stability of the shoe, it remains flexible enough to satisfy all you mountain goats out there. The tongue is still attached to the medial side of the upper eliminating slippage and reducing the risk of chafing. The 4.5 still comes with a stone guard accessory as part of the deal. When inserted, it provides extra protection from any rough terrain. There has been no change to the outsole, but one reviewer commented that it provided improved grip. This is possible because the firmer mid-sole will tend to anchor the outsole better.
So while the tougher upper and the firmer mid-sole will make this shoe more attractive to a wider range of trail runners, it is still not especially designed for technical or ultra trail runs. However for shorter or easier trails, this shoe has few equals.
