I've been using these for a few years and love them, I do not attach them in any which way to my skates, this way I can remove them after playing to air them out (they're pretty absorbent so I'd imagine they'd stink real bad in a short time if you didn't air them out). I just slide them in before I put my skates on and push them to the top of the toe cap, the foam sort of takes the shape of the cap and keeps it in place until I slide my foot in, once your foot is in it's not going anywhere, I've never had issues doing it this way and see no benefit of physically attaching them.
