Abercrombie and Fitch sandals

Abercrombie and Fitch brown leather T-strap style sandals. I have had them for a while, but I have only worn them a handful of times. The liner around the straps seems to be coming apart as pictured, I don’t think they were like that when I originally bought them. Not sure if it will affect their wear or not. I also cannot find a size on these, but I’m assuming they are a size 8 since that is what I wear.
