Our verdict

The Ultra Raptor GTX is all about long days in the mountains and preferably wet and muddy hills. Solid and well-cushioned, they'll protect you but they are heavy.

First impressions

These are shoes that will surprise you; bulky and heavy feeling on that first in-shop fitting, you’ll probably think they won’t cope with anything too serious. But take them out on the trail and they’re surprising, well cushioned and pretty responsive. 

They certainly look the part. The sturdy mesh uppers have significant overlays to protect and strengthen the shoe while keeping your foot locked in. The outsole wraps up to create a big toe bumper and the shoe also features a significant heel counter. 

On-foot, the feel like a road shoe due to the ride height. The tonge and heel areas are well padded and they feel comfortable.


Sure, they’re not racing snakes but actually the fit and general cushioned feel makes them feel pretty lively and capable of a good clip thanks to the lightweight, forgiving midsole made from injection molded MeMlexnand nylon molded flex transfer shank. They are a wider feeling shoe sitting high on a 12mm drop so take note of that. Some of you out there won’t like the bulk


There’s AirMesh, an abrasion resistant microfiber, HF lacing harness  and a TPU transkinetic heel stabilizer, all of which creates a mightily stable platform. For a neutral shoe, this offers a lot of support and means they wouldn’t be too bad on the road. Of course, the Gore-Tex lining means they can cope with mud and rainy days.


While the grip, perhaps a bit slippy for road, comes via the Frixion XF outsole. We liked them on forest paths, indeed they quickly became the shoe of choice for easy afternoon runs where pace wasn’t an issue, thanks in part to that flexibility and also the support offered.


The Ultra Raptor GTX are all about long days in the mountains and preferably on wet and muddy hills. The shoes ran really well, but due to the 12mm ride height, they feel like a traditional road shoe which will be welcomed by some, frowned on by others depending on your terrain. Obviously, the higher you ride, the less stable the shoes are likely to be. That said, these shoes will keep your feet dry, offer exceptional grip and give you a well-cushioed ride around your favourite off-road tracks.
