I eye the things in my hands skeptically. Two runners, each a meter long, with a wheel at either end. Basically, a cross between skis and inline skates. And that’s exactly what they’re supposed to be. These so-called roller skis are used for cross-country ski training during the summer months. And not in an indoor ski hall, either: thanks to the wheels, you can use them right on the asphalt. Sounds simple. It isn’t. At least not for me.
