Is the Columbia Konos TRS Outdry really waterproof?

Yes. The OutDry membrane is bonded directly to the inside of the upper, so there is no gap where water can pool. It keeps feet dry in rain and wet grass, though water can still enter over the collar in deep crossings.

How does it compare with the standard Konos TRS?

The Outdry version adds the bonded waterproof membrane and a slightly more protective upper. The standard Konos TRS is lighter and more breathable but not waterproof.

Is it good for fast hiking?

Yes. It is light, flexible and cushioned, which suits a quick pace on day trails. It is not the right pick for heavy packs or steep, loose terrain where a stiffer boot helps.

Does it run true to size?

Most hikers find it true to length but on the narrow side. If you have wide feet or wear thick socks, consider going up a half size.

What are the lugs like for mud?

The 4mm lugs are shallow. They grip packed dirt, gravel and wet rock well, but they fill up and lose bite in deep mud and loose scree.

Can I use it for trail running?

It works for light trail running and fast hiking, but it is heavier and stiffer than a dedicated trail runner. Runners who want ground feel will find it overbuilt.
