Depends. When I had a big leg day, and a tournament the next day, what I would do is ice bath after leg day and wear my compressions. I'd be legit good to go the next day, soreness was almost all gone. I've done it with just the ice bath/no compression, and I'd still be a bit sore. The compressions don't completely "change the game", but they're a good supplement if you've got a heavy lifting schedule.
