I bought the Steel Series Rival on August 10 2019. Based on the other reviews, I purchased size 9 and they fit perfectly. My headset was sliding back and forth on my head and it was obnoxious to wear. After 3 similar products this one actually works. This is my second pair of these sandals. Charged for 6 hours and still not turning on. Im not sure if it is the boots stretching to fit my feet or my feet adjusting to the boot but it is getting better. Beats paying $280 OEM. I got half a size bigger as I thought they might come small but cant even get them on and Ive not even got wide feet! That was before attempting to drive in them which I can only call dangerous!
