TTS is a terrible term. I'm not sure what you mean by half a size bigger. If you mean that they run half a size bigger, I think that is the general consensus. I've never tried on Lindricks, but wear my Marlow wingtips and full strap penny loafers half size down from my Brannock size. If you have wide feet I would go with your Brannock size. Half size down will be too small for you IMO. Not sure if I would go half size up from Brannock.
