The Flex Runner PS 'Laser Blue Crimson' is a preschool shoe with a vibrant look. The shoe's slip-on construction appears in Laser Blue on the stretch textile upper, with black contrast provided by the synthetic leather overlay. The Swoosh, lining and pull-loops further highlight the look, with the latter elements providing easy on and off. Underfoot, a white foam sole unit with flex grooves on the outsole anchors the build.
