Feels like the Tracer runs a 1/2-size smaller than the Clayton (I'm a size 12). I do all of my runs (outdoor, treadmill, 50-120 minute aerobic and some tempo) in the Clayton and like them a lot. I used to run in Brooks Pure Connect (and still would rotate through these hadn't they been discontinued). I just did a treadmill speed workout in the Tracer and instantly felt a slight big toe pressure due to not enough length. I think going with an ultra-thin sock will help with that shoe length issue. The Tracer's overall shape is more of a traditional shoe fit all around whereas the Clayton's look like miniature snow/clown shoes. Surprisingly, the Clayton isn't that much heavier than the Tracer (or that they didn't make the Tracer lighter). My usual racing flat is the On Cloudracer and doubt that the Tracer will replace that for me. I'm still looking for a lighter racing flat in the 5.5-6.5oz to replace the On for 2M to 1/2-mary distances.
