The first thing I do when I check in to a room is take the shoes and dirty laundry out of my luggage, opening the dirty laundry bag to let it air out and taking the shoes out of their bag as well. I've always worn breathable canvas-top or mesh-top shoes along with odor-resistant Dickies work socks, so smelly sweaty shoes aren't really a problem even when walking 10+ km a day in a hot & humid climate.

6 shirts and only 3 pairs of (boxer) shorts? I always change one when I change the other. Normally I wear my sneakers and pack my sandals, but if it's wet outside, then the sneakers go in the bag to stay dry. Also, I chose to pack a lightweight puffer jacket instead of a hoodie. It weighs less and is far more effective at retaining heat.

Southeast Asia is a very open-air place, full of cooking fumes, exhaust fumes, burnpile smoke, sewage smells and other unpleasant odors. A little sweat smell is not going to be noticed unless you're in a confined space - then you can put on some deodorant that smells like restroom cleaner. Speed Stick Power Fresh is my go-to for bus rides. It's dirt cheap and carry-on sized. If you get sweaty on a morning hike, A/C turned on high dries out a T-shirt pretty rapidly.
