I bought these running shoes online from the mizuno store in 2023, with hopes they hadn’t changed their wave runner shoe from 2009 when I ran the SF Nike Women’s Marathon. I stopped running because of Achilles tendinitis and this shoe was the only one that didn’t aggravate my condition. Sadly they are too big and gave my a blister on my right heel. I am a 6 1/2-7 shoe size and sized up for running shoes. I’ve worn them 2x and they just hurt my right heel. Maybe you will have better luck 🍀
