Custom fonts not working

I created a sub-domain as a micro-site for the main site: https://breastcancermarathon.com/

There are a few custom fonts coded into the site – one of which is used for icons. It appears they pulled over with the migration but they are not appearing/showing properly.

Any ideas on how to fix this or why it is happening?
