10 is probably your TTS yes. Nike and JB historically run small because they are meant to be tied tight and balled in first and foremost, and yes you can not lace them up as tightly, or loose lace for an off court and more casual look.
RE the forum, I think most forums are dead these days, everyone has moved to facebook for instant...whatevers. Doesn't help that the new forum software is pretty wack, i've seen it many times, forum using VBulletin or whatever (pretty much universal form software) everyone knows how to use, forum gets upgraded to something new someftware, usually some bespoke thing to be fancy, everyone hates it, it wack to use, traffic drops to practically zero, forum dies...
As to Jordans releases, wouldn't know, where I live you just can't buy them. have wanted a few over the last few years (I only really like OG's and pretty much 1,4,5's).
Nowhere locally sells J's, need a plane flight to the nearest store, online sells out in nano seconds, so left with getting fom the US (add $50 post from US to Australia) from ebay or resellr for 3x retail..not worth it, so basically I don't buy J's any more.
It's going to be extremely hard getting accounts that will allow you to sell the most sought after sneakers. You can probably get an account selling all the regular styles. Even with that, the big companies won't really mess with you unless already have a brick and mortar and is proven. Plus they've been trying to cut the middle man so you can't be just a regular store.
