Nessa Slip-On Sneaker (Women)

I've had an older pair of Merrell's for many years, but the sole became separated from the shoes after years of wear. I ordered a replacement pair in my regular size, however they were too big after they arrived so I returned in exchange for a pair 1/2 size less. When those arrived, initially they fit well so I wore them outside. Unfortunately they have stretched a little and I am not going to be able to wear them because they are not comfortable anymore (move on my feet). Too late to return them, of course, so I will have to go without them because I can't afford to shell out that kind of money again. It's sad because I have relied on them so heavily over the years and this was just wasted time and money.
