I just tried on some TF7s. My MLX are a size 10 and my right foot, which is slightly longer than my left, touches the toe box with slightly more than feathering pressure. I tried the TF7s in 10.0R and was swimming and felt like my arch didn’t line up with that of the boots; 9.5W felt like I could sharpen them and go without any baking, though the heel felt a bit relaxed; 9.5R felt on the money: snug, with even pressure everywhere except across the forefoot—there it was a touch too tight, but I’m confident a bake would fix that—toes were feathering the toe cap more ideally than they do in my 10 MLX. Now I wish I had tried 9.0W + R, but that’ll have to be for another day.
