What is the difference between MBTs Dual Board (lower) and Integrated Shank (classic) sole?
The new Dual Board (lower) sole provides the wearer with the same benefits as the Integrated Shank (classic) sole – the only difference between the two sole constructions lies in the feeling for the wearer. While still curved, the Dual Board construction reduces the heights of the sole by approximately 8mm, offering a new slender look and additional style choice to customers.
