I take a true size 9 in a shoe/boot. I ordered the 9 Ektio and found they run a half size small. They don't offer a 9 1/2, and probably would be better off with a 10 (which would fit like a 9 1/2), but I used a very thin liner sock in the 9's and find I can get away with that size. I've rolled both ankles within the last couple weeks playing singles pickleball, and knew it was only a matter of time before I seriously sprained an ankle. Since playing in these shoes, I'm not afraid of running laterally, or quick change ups. They support my ankles, don't feel bulky,and give me the confidence of going all out without the fear of injury. I've only put 8 hrs on court so far, so time will tell if they hold up.<br />If only they had half sizes in the smaller size shoes, hence 4 stars.
