Hi there! It looks like you have either our S351-21, with a 15-002 bottom attachment, or S390-21, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a spring strength option of 2030. If you have any further questions please let us know! Comparison of the S351 and S390 balance shoes.

Yes, the S390's metal channel's width is 9/16", but is considered 1/2" in the trade. |
