How do One Star Pro fit compared to a Chuck Taylor or Chuck 70?
One Star Pro runs slightly smaller and shorter than both Chuck Taylors and Chuck 70s on the same size. The cleanest cross-Chuck owner comparison comes from a 7.5 owner who wore the same size in all three: "they fit a tad smaller than regular chucks and a 1/4 to 1/2 shorter than Chuck 70s" with the OSP being the tightest first one-star after owning many chucks, these being the tightest. If you already wear Chucks TTS, hold the same size but inspect for toe-box snugness before final-sale buying; if your feet swell during the day, go half-size up.
