When I first bought my sneakers, they were uncomfortable. They're wide on the side and kinda tight on the top. But, well.. I paid nearly $60 for it, so... there's no way I'm taking them off!
But, after wearing them for more than 2 months, they're actually comfortable now.
Mine is these high heel shoes but the bottom is like a sneaker, so you have grip.
I went to the laundry after work and boy didi find out how it feels after 3 hrs straight on your feet.
