Familiarity: I've put it through the wringer
I wear this shoe on 80% of my climbing endeavors. It's comfortable enough for extended wear and yet has enough performance features to allow me to succeed on more challenging climbs where I might normally be compelled to where a more technically advanced shoe model.
The velcro closure makes it extremely easy to put on and take off, and allows me to get a precise and snug fit when needed.
Mad Rock's rubber formula keeps improving and this latest advance is no different; allowing superior "stickiness"while also lasting longer than previous formulas.
If you're looking for a new shoe, I suggest trying the Flash 2.0...you won't be disappointed.
