Asics gel infused runners

These were recently purchased on Poshmark. They are a size 5 US on the tag. They are actually sized as a 6 US. if you go by the European measurements, not a 5 US. It was a manufacturer error. My wife has many Asics sz. 5 runners, and we compared the tags. They are in excellent condition but unfortunately too big for her sz. 5 ft.
