Is the Terrex Skychaser AX5 GTX truly waterproof?

Yes. It uses a Gore-Tex membrane, and owners report dry feet in rain and wet grass. Water can still enter over the collar in deep streams.

How does it compare with the Terrex Free Hiker?

The Skychaser is lighter and lower-cut, with a more flexible feel for fast day hikes. The Free Hiker is heavier and more cushioned, better for long days and heavier loads.

Does it fit true to size?

Most owners say it fits true to size, and it comes in medium and wide widths. Those between sizes or wearing thick socks often go up a half size.

Can I use it for trail running?

It works for light trail running, but the 12 mm drop and shallow lugs suit hiking better. Runners wanting aggressive grip should look at a dedicated trail shoe.

What is the drop and cushioning?

It has a 12 mm heel-to-toe drop with an EVA foam midsole and an Ortholite insole. That gives a soft, stable ride for walking rather than a ground-feel trail feel.

Is it good for multi-day backpacking?

No. The soft mesh upper and light cushioning suit day hikes and light packs. Multi-day trips with heavy loads call for a stiffer, more protective boot.
