US sizing. As part of the Glide product family, the Bondi 9 has ample cushion, but now with a springier feel, thanks to the EVA being manufactured with high pressure, temperature and nitrogen, creating a more responsive feel. The drop is one millimeter bigger, and stack height two millimeters thicker than before. The cushioning is still ample, making this model the right choice for those for whom a plush feel is more important than light weight. The Bondi is a good choice not only for running and long walks, but also use as a super comfy pair of shoes for casual use. - For a neutral stride - 5 mm drop - Durabrasion reinforcements on the outsole offer great service life - Breathable surface fabric - Moisture transferring liner made of recycled fiber - Ortholite sockliners - Supercritical EVA midsole
