Hey there!

Based on what's shown in these photos, I recommend our S380-28 or S385-28 channel balance. The crucial difference between them is the depth of the bottom shoe as shown in the image below. Measure yours to see which one matches up. You will also need the 2730 spring strength option. 

Comparison of the S378, S380 and S385 balance shoes.
