Had another pair in another color and wore them for for four years before the tread gave out. I give only 4 starts, because after 1 month the Puma print is losing and fading away. The spatial awareness in the 100s is outstanding. They are all mine mine mine! I had not really paid attention to this, but when I first got this bar I realized my old bar was thicker. App is slightly buggy but not unusable. it just fits nice around your arch without you knowing. Molto belle, come da foto. The new Flyknit material feels great so far (only 10 miles in) as its light and very breathable which is welcome here in TX. The color was a navy blue.
