I've only handled AV_Field, no L0, but they were made by Alessio. All the pairs I've had are built like tanks. Very tight fit around the toe box though, so be wary about going TTS. That and the laces, while cool, are a major pain in the ass to do up and have a habit of coming undone. I've been caught numerous times trailing a good metre of shoelace behind me as I'm legging it somewhere.
