KSwiss 7 1/2 gray memory foam heel sneakers only worn a few times

I got these sneakers as my backups for when my other ones gave out. I wore them a few times when I wanted nice looking sneakers instead of old ones, then covid hit and I never wore them, got pregnant and always wore slides or boots. I just wore these a day or two not too long ago, and they now don't fit since pregnancy. Still in great condition. The wording on the inside heel has worn off, but the laces and soles are in excellent condition and the shoes themselves barely look used
