Ya the reddit post alluded to custom orthotics, and the link to Aetrex from @mojo122 seems to confirm. I might have a use case for that, but to be honest the Speedplate 2.0 is very very nice imo.
Edit: looking at the document from @VegasHockey, the orthotics actually look pretty cool when paired with the Aetrex. I did not realize the base of the Aetrex was soft and conforms to your foot. Although you have 3 options of orthotics, so if you've been skating long enough you can probably guess which one you'd need.
