Men’s size 11.5 Nike InfinityRN 4. I don’t have a mileage for them as I actually just use them for “time on feet” shoes when I’m coaching. I did one 3 mile treadmill run in them and I think maybe one more 3 mile outdoor run, but can’t remember. So any real use has just been “wearing them”. Comfy under foot for sure, the upper just doesn’t quite work for me and how I wear them. Let me know if you have any questions.
