Are these SIDIs supposed to hurt

My pa didn’t want a pair of SIDIs he got on a bargain table real cheap (we have small feet, small enough they don’t get sold a lot and put on sale). They are the road version with three velcro straps, and I gave them a try and to be honest, they felt worse then my 10 year old Specialized El Gatos. They were worn once then tossed aside, do they need to be broken in?

I figured putting them on would be a like the equivalent of a blowjob for your feet.

The only reason I even bothered with them is because my el gatos are starting to literally fall apart and when winter comes I will need a better shoe with proper circulation.
