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. With enhanced function of WaterproofPlus, our highly breathable waterproof membrane, feet stay dry by keeping water out and allowing excess heat and moisture to escape. By maintaining the recognizable blue DuraShocks SR outsole pads, this boot continues to deliver what weve all come to love with its overall weight and fit.
