I only run in Lunarfly+ 3 shoes (I actually have three pairs) and wanted to try the Breathe version. Naturally, buying these on Zappos gives you a great discount and awesome free shipping. As far as the shoes are concerned, they are basically the same as other Lunarfly 3 shoes but much lighter. I usually run with socks so could not notice if my feet actually breathe better or not but the shoe is awesome lightweight and looks cool. If you like Lunarfly 3 shoes, I recommend these as they are lighter than the normal version.
