I am a big fan of ASICS brand's running shoe. I used to have a Kayano 21 which is my favorite shoe ever. However, Kayano was discontinued more than one years ago. I got new pairs of  running shoes, Kayano 23, it still looks nice and very light weight. However, it somehow does not comfortable as 21. It still reduce the pressure on foot surface, that why I gives 4 stars this time. I still love this brand, best brand for running shoe.
