First impressions of the Impact were good, with great levels of padding throughout the upper and particularly around the ankle, balanced out with a stiff heel section. This combination of soft upper and hard sole makes them a decent bet to be worn year round. On harder ground and road sections, the hard sole can jar a little, as the midsole shock absorption doesn’t quite cushion the blows. The rubber rand around the toe helps to protect the suede and a reinforced heel helps cover your ankles. The sole unit has been specially designed to deal with rocky terrain, and was found a little wanting in muddier terrain, with forefoot grip suffering, especially on muddy slopes.
