For a more summery version, we opted for Vibram Gumlite.
The rubber used is expanded, making it 40% lighter than traditional rubber. The result is a more supple, airy ride.
The sole remains true to the House's reputation, with the same insulating and gripping properties as traditional Vibram.
The question remains, however: do we really need a highly grippy sole in the middle of summer? The weather is generally milder (unless you're lucky enough to live in Paris, that is) and it's common to prefer a smooth leather sole, which is thinner, lighter and less hot, especially on unlined moccasins, which are therefore more flexible.
