Last weekend I went to Marseilles via the Camargue (photos will be posted this weekend). It was the ideal occasion to test out a pair of Soubirac "Kliper 2" motorcycling boots.
As you can see, they look more like army boots than normal riding boots. That's not surprising, since Soubirac supply the French fire brigade, police and armed forces. So that means that they should be solid enough for motorcycling.
