TTS and you'll be fine. Sizing down would be a disaster. I had a chance to try on a TTS large, and while it is a tag long in the arms and body, the fit is perfect. Unless you wear extremely tight jeans sizing down would make it look poor in the body. Keep in mind its supposed to fit on the longer side of things.
Exactly why I posted it. Not really my cup of tea, however if it were in black or grey I might be inclined. That blue is too flashy, not to mention theres already too many details on the jacket it would look gaudy with my style.

Those black ones were always fire. Ever since I saw a girl wearing them on a tumblr shot I knew they were sick. Too bad about the nylon though, I don't know if I would buy them, too many tech materials, the patent is already a little overwhelming.
prob 8. I wear a 9 in lanvin and cant do 43 mmm, too snug in the toebox. I also wear a 43 in CP 44 in pierre hardy.
Also, the only issues i have with mmm as opposed to cp is that mmm sole is glued, and without the stitching, tends to loosen after a long time.
