It might be hot tightly you're tying the laces. The shoelace eyelets are straps that wrap around the foot. If you cinch the laces as tightly as humanly possible, your feet will feel it.
I just pull all the slack out of the laces and that's as tight as I need it. I cinch the top, very last hole and that's enough for me.
