No ... When the OP arrives in a few weeks, Bangkok will be more like mild and balmy, not hot and humid.
At noon today in Bangkok, temperature was 89f/32c with humidity of 65%.
In Bangkok, during November-January, there may be some evenings cool enough that you want a light jacket -- which you can easily buy here.

Bad advice for Bangkok.
Most tourists walk a lot.
Bangkok pavements are horrendous: cracked, broken, uneven, lots of holes, pipes sticking up, scattered garbage, and dog poop.
Wear shoes suitable for walking a lot in those conditions.

Tourists go to only a few temples, and not every day.
Every tourist temple has benches where you can sit down to remove/put on shoes.

I've never seen a shop yet, where shoes weren't allowed in.
The staff may leave their shoes outside the door, but customers walk right in.

As for private homes, very rare for tourists to be invited inside a Thai home in Bangkok: It's just not their custom.

So, best to wear shoes for walking the streets, not for the odd chance you'll need to leave them outside.

Perhaps so, but I've never seen nor heard of any.
The custom in Thailand for "polite shoes" means a strap around the heel.
The toes don't matter at all.
(High-toned night clubs for the young-and-hip will have their own dress codes, of course.)

I've read endless warnings along these lines on Internet forums, but in two years of living in Bangkok, I've never seen anything like this actually happen.
Would expect this in bars where Thais and foreigners and alcohol mix.
But in a tourist experience, very rare.
