Thanks for your photos. Based on what I see here, you have either our S351-18 or S390-18, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

Comparison of the S351 and S390 balance shoes.
