Hello MegsFulls501,
Thank you for using Apple Support Communities! I understand that you would like to know if there's a way to track how much distance you've run on a pair of running shoes when working out with your Apple Watch. I would be happy to help provide options to consider.
When using the built-in Workout and Activity apps, there's not a category specifically for workout gear. However, one option would be to create an 'Other' workout used specially when wearing the running shoes, then name it after the shoes worn:

Another option to consider would be to use a third-party app, such as Nike Run Club, that allows you to add and track how many miles you've run in your running shoes:
Cheers!
