Purchased 6.7 years ago and used a few times for commuting, but I'm selling it because I no longer have the opportunity to use it. There's a slight rubber smell, but I don't see any deterioration. There's a little gravel in the soles, but I'll send it as is. The size is L. The insole size is 30.5cm, and the length is about 40cm. I usually wear 25cm sneakers, and these fit just right or have a little extra room. I think they're good for sudden rain. Please purchase if you understand.
