r/RunningShoeGeeksⓘ good to know

“I still have the B12, already ran 300+ km in them. With the foam on my B12 already matured and compressed with such mileage, it is slightly softer than my new B13”

r/RunningShoeGeeksⓘ good to know

“My 9.5 in Adidas world is in fact 9 2/3 and is too roomy. But 9.0 is TTS and is definitely small.”

r/RunningShoeGeeksⓘ good to know

“It's the only shoe I've ever had to size down in. Always always a 10.5 but was a 10 in my B12's”
