Hello,

Thanks for posting! The balances you have here can be replaced with either the S351-21 or the S390-21. To determine which of these is the correct replacement, you'll need to confirm the depth of your bottom shoe.

You'll need the 2030 stamp option.

Comparison of the S351 and S390 balance shoes.

Hello Jasmine,
Thank you for the info. You have really saved me a lot of time and research. I've ordered (4) S390-21 with 2030 - stamp option.
The help you provided gives me confidence in placing the order and they will work.
Thanks, John
