Need some advice/help here. So I’ve got this smooth raised portion on my skis, didn’t hit anything, no top sheet of edge damage, not near bindings. These skis are pretty new, doesn’t seem like an iron bubble. It is not like a bubble really, as it is firm, but it is slightly raised. Weird shapes. You can kind of feel it when running hands over base. Any thoughts? Shop had no idea what it was. Think it’s even an issue?
