Thanks for posting! Before I can offer an applicable replacement for your channel balance, we just need to know a bit more information.

First, what is the length of the metal channel? Please do not include the plastic attachments in your measurements.

Finally, we will need to know what type of bottom shoe you have. Please refer to the following chart and compare the examples shown to your own attachment. Which one best matches your shoe? Keep in mind that while a fraction of an inch difference may not seem like much, it is important to the function of your balance.

HI

The channel is 32" long.

I have a winged foot 15-004.

Please advise

Thank you.
