Packaging: they came in shrink wrapped plastic, no box. Opening it revealed a bad plastic smell. I'm sticking them in the garage with fabric sheets to air out.Size: My foot is 24.5 cm long, I usually wear a 7.5 in men's. So I ordered a 7.5 (41) and it fits perfectly. However if you have a wide foot, it may not for you.Comfort: they're well padded inside, and have a slight spring when you step. Time will tell with walking.
