Updates to the Salomon X Ultra 4 Mid GTX

The 4th-gen X Ultra Mid GTX comes with several improvements over the Salomon X Ultra 3 Mid GTX. These enhancements are as follows:

Weight decrease. Compared with its predecessor, the X Ultra 4 Mid GTX is about 50 g lighter per pair.

More heel support. With its cushioned Achille’s rest, this iteration provides increased heel security.

Rearfoot flare. The proprietary outsole of this hiker comes with a heel flare—a component that makes heel landings safer, allowing for glide-like strides.

Environment-friendlier. Unlike the shoe it succeeds, the Salomon X Ultra 4 Mid GTX is engineered PFC-free. PFC or poly-fluorinated chemicals, as discovered by modern scientists, can negatively affect hormone levels and cause reproduction problems.

Salomon’s X Ultra 4 options

As compelling as the X Ultra 4 Mid GTX sounds, the boot in question is just a third of the X Ultra 4 lineup. Yes, two other kicks make up this compelling collection, namely the X Ultra 4 and the X Ultra 4 GTX.

Both of these options are mobile, low-top offerings. That said, the former revels in its high breathability, while the latter is a competent wet-weather companion.

Takeaway: Choose the X Ultra 4 for summer hikes, its GTX counterpart in light rain pursuits, and the X Ultra 4 Mid GTX for extra-daring adventures in more inclement conditions.
