What is the difference between the Premium Mats and the 3/4" Shock Mats?

The main difference between our Premium Mats and our Shock Mats is the thickness. Other differences are the size options; the Premium Mats come in one size versus the three offered in the Shock Mats. Both mats are vulcanized, but the Shock Mats have a waffle-backed design that helps to reduce noise transmission from floor to floor and helps to reduce impact.
