Long story short, I’m an idiot. I assumed this was the correct size for me and didn’t try them on until beyond the return date. I put 5 treadmill miles on them to get a feel for them before my marathon next weekend and quickly realized I had messed up. Super clean, 5 treadmill miles only. Smoke free home. Let my mistake carry you to a PR! 🤦‍♀️😅
