I've been buying Asics shoes for about 20 years. Lots of couples. Always buy 12.5 million. These 12.5m cross training shoes fit just like running shoes. They endured weightlifting and short sprints for up to eight months. Nice flat heel so you don't end up in a weird position when crouching. They are easily worth the $45 I paid for them in June 2013. Looks like they've gone up in price a bit since then.
