Are trail running shoes suitable as hiking boots in the Alps?
Using the La Sportiva Cyklon Cross GTX – comparable to the Scarpa
Ribelle Run Kalibra G – the question arises:
Can a trail running shoe replace a classic hiking boot?
The short answer: Yes.
But taking a closer look at the pros and cons is worthwhile.

Weight – the biggest advantage
One of the most important differences is weight.
Trail running shoes are much lighter than traditional hiking
boots. And in the mountains, the rule is: everything you don’t
have to carry saves energy. A clear plus for trail running shoes.
Flexibility on different surfaces
If you’re planning a hut tour with long approaches or have to run
asphalt sections in between, you’ll quickly notice: stiff hiking
boots are rather uncomfortable.
Trail running shoes score here with flexibility and offer more
comfort on changing terrain.
Water protection and shaft height
A disadvantage of many models: most trail running shoes are only
low-cut.
If you suddenly have to cross a stream without a bridge, your feet
will get wet quickly.
This is where models like the La Sportiva Cyklon Cross GTX or the
Scarpa Ribelle Run Kalibra G offer advantages: they are waterproof
and reach over the ankle – so your feet stay dry even in deeper
streams.
Protection and stability
Hiking boots are more robust, especially around the ankle.
However: you can also twist your ankle in a hiking boot with one
wrong step – so there is no decisive extra protection.
If you often bump into rocks on narrow trails, you’ll benefit from
the thicker padding of hiking boots.
For mindful, sure-footed walking, however, the difference is
minor.

Durability in rough terrain
One weak point remains: durability. On tours in the Karwendel, where there is a lot of scree, I quickly noticed the first signs of wear on my La Sportiva Cyklon Cross GTX. The result was a small hole at the upper edge. Robust hiking boots usually last longer here.
Conclusion – Who are trail running shoes suitable for?
For sure-footed hikers who value low weight and flexibility, trail running shoes with a higher shaft and waterproofing are also a very good choice in the Alps – even for hut tours. However, if you are looking for maximum durability and lateral protection, classic hiking boots are the safer bet.
