- Shoe fits well on the foot
- Too stiff for longer runs
The Mammut Sertig II Low is a very stiff shoe that rolls quite well uphill. All in all, it is a very stable shoe that doesn't make you want to run, as it is simply too inflexible on the flat. You notice that it is more of a speed hiking or light hiking shoe than a running shoe. The lacing is very tight, but not too comfortable...
