Balance Question--worn down shoe?

A home owner from USA says:
Please confirm. I think the replacement balancer for me is the 27" series 385, S385-27, option 2640. The bottom shoe mic at 1.075, maybe some wear?? With the pics I sent is that your recommendation?
Thank you for your time and help

Wear is pretty normal. If your shoe is over 1", I think it's likely that you once had a 15-004 shoe that simply wore down to its current depth. The S385-27 is a great choice based on your specs.
