Brief Answer:
Unlikely to cause interference. You can use them.

Detailed Answer:

Hello,

Let me assure you that the magnetic power of a magnetic insole is very less and is not likely to interfere with the functioning of the orthotics. Most orthotics are significantly made of non-iron parts and therefore problems are unlikely.

However, it would be helpful if you could provide details about what sort of orthotics you use. Based on that, I would be able to guide you further.

Hope I have answered your query.
