The idea behind the MFS Vakuum^® styles is to combine a stable outer boot, providing security and purchase, with a particularly soft and adaptable inner boot. The special foam is used in the entire boot, thus adapting perfectly to the whole foot.

Also particularly impressive is the elasticated GORE-TEX^® in the heel area, which means there are no seams at the heel.

The footbed adapts to the foot and it simultaneously provides very good support.
