Air Cushion

A patented air cushion midsole that absorbs shock and improves stability.

Exclusive to Merrell footwear, this patented air cushion is engineered to compress on heel strike and absorb shock up to four times the body’s weight for effective cushioning and comfort.

Meanwhile the pronounced heel cup shape helps to keep the heel centred in the boot for greater stability in every step.

The Merrell air cushion offers the same comfort and cushioning of a running shoe combined with the stability and control needed for cross country walking.
