I was worried at first that they might be too tight (even on the loosest setting) but after like an hour of wearing them they already started to soften and stretch out just enough to feel magical. The mechanical feel of the keyboard may take a little getting used to, but for me it harks back to the old days where all keyboards were built this way. Good traction on sole and adjustable for swollen feet . I can tip my head to the side and slap the side of my head until I have a brain contusion, and they dont slip at all. These feel like im wearing slippers. I have a larger head and it fits so well. These headphones can be worn over my hearing aids and behind the head. Shoes were packaged well and clearly new in box. Really not that bad to install! I returned these shoes.
