Since it was first introduced in 1998, the DuraShocks SR boot has been a best seller because of its iconic styling and guaranteed comfort. We're improving this best seller with the DuraShocks SR Icon by creating wide, more cradle-like heel in the midsole that gives you that extra cushioning for improved stability. An updated CarbonMAX composite-toe provides lightweight protection that doesn�t get hot or cold as the temperature changes. And by maintaining the recognizable blue DuraShocks SR outsole pads, this boot continues to deliver what we�ve all come to love with its overall weight and fit. Power through your day in the Wolverine DuraShocks SR Icon.
