Thanks for posting in our discussion board! Before I can recommend an applicable substitute, I just need a bit more information, namely regarding your bottom shoe.

Please refer to the following chart and pick out your shoe from the examples given. This will help us identify your balance Series.

A home owner from Arizona says:
The shoe has NO wings and the width is 1".

Thank you for the clarification! However, are you sure that your shoe is 1"? I ask this because based on your picture, the style appears to be closer to our 1-1/8" 15-001 shoe. It is, of course, impossible for me to tell by the picture alone. Can you please double check your measurement? Is your shoe closer to 1" or 1-1/8"? I apologize for the inconvenience.

It could be 1-1/8". When I measure it with my "highly" precise tapemeasure (pun intendend)it looks to be 1-1/16"

Thank you. I think that should be all the info we need to get you started! With a winged top and a non-winged bottom, you will need the S395-28 with the 2730 option.
