La Sportiva's No-Edge technology 

No Edge shoes offer effective protection for the rand by incorporating an additional layer of sole rubber that extends up and over the top of the shoe.

This extended sole design makes wear in the toe area much more visible, so once you’ve worn through that section it’s an obvious sign that it’s time to resole.

 Send shoes in when the rubber wears through, but before damaging the rand.

The No-Edge sole is replaced as a whole piece, rather than grinding down a traditional sole.
