I'm sorry, I'm not sure which dimension in particular it is you're referring to. Do you mean the heel-to-toe meaurement? If so, then it's common that these shoes wear down a little over time.

Thanks for confirming! Like I mentioned, it's possible the shoe wore down. Even if that's not the case, the 15-005 is actually the smallest option we have. If you absolutely need it to be 7/8", you can always shave it down a little.
