Thanks for your photos. Based on what I see here, you have either our S380-11 or S385-11, 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 S378, S380 and S385 balance shoes.

My sash is 6.5 LB will the 1010 option work or do I need the 1020 ? It is a small 20"x 13" sash

If your sash is over 6 pounds, then I'd go with the 1020 option. This carries 6 through 9 pounds, which fits your sash weight perfectly. The 1010 option would fall under your stated weight.
