The problem with fit recommendations is that a) everyone has different feet and b) everyone has a different idea of optimal fit. I tried half size down on 1010s and my toes were scrunched, totally not a viable option for me.
Also I doubt most people saying TTS have actually measured with a brannock device, and are just going off what sneaker size most commonly fits them
I'm an 11C in actual measurement, but nearly any athletic shoe I've tried fits way small and I have to run 11.5D, sometimes 12. And my Red Wing boots are 10.5...
You're going to confuse a lot of people who know their actual size, saying TTS when you have no idea what your actual size is.
