Halara waffle pants reviews? Are they worth it?

I keep seeing Halara waffle pants recommended in teacher subreddits, and so many teachers seem to swear by them. I’m tempted to order a pair, but I’d love some honest reviews first.

Are they comfortable for standing and moving around all day? How do they hold up after regular washing—any pilling, stretching, or fading? I’d also appreciate thoughts on sizing and whether they look professional enough for the classroom. Thanks!
