Ya Im size 13 6ft5, and the rough range of board dimensions that works for me is 8.25-8.5, 31.8-32.25, 14.2-14.5
On ventures usually. Can do all the other major truck brands if needed, will probably just complain about kingpin clearance or pinch or some shit
It depends on what you skate. I skate almost exclusively ledges, flatbars, curbs, flatground. Occasionally some banks, transition... and handrails if I'm trying to get a clip. If I skated all the latter stuff more, would definitely err towards the bigger end of my setup preferences
The thought of skating an 8.75 thats over 32.5 is crazy to me. Sure, its comfortable to ride. But its also just so much more work to skate.
Bigger boards are more effort to maneuver, but also more comfortable to land on. While thats true for me too, its also often the case that I find it easier to stay over the board and be ready land properly if my body doesn't have to do the absolute most to form the trick, which often is the case with big clunky boards.
Thats just my preference though, there's also a lot of technical stuff I find easier on a bigger board, but not that big haha
I can't tell ya whats best for you. If you feel you can't get used to a board that feels too small, then try something bigger again.
Or, figure out what part of your form/technique thats causing you to land on the nose or whatever. Maybe try bring your front foot a bit further in, or slide it less etc. If that works it works, and you may experience some benefits of a smaller board. If adapting isnt working, then fuck it, ride what works for you and dont force yourself to figure out something that feels wrong.
As far as trucks go, you could try different trucks. But it also could be that your wheels are too big and clunky or something... not to add another dimension to the madness.
Shoe wise, new balance cupsoles, or any cupsole that has an actual midsole and a decently structured upper that fits well is good.
I like jordan 1s with the right insoles, and tiago 1010s. But best to go to a shop with a few models that meet the above criteria, and see whats most comfortable on your foot.
