Jean, I have to ditto Kristine. I own a pair of olive green Privos that are as comfortable as sneakers and that I wear EVERYWHERE when I need something sneaker- like ( I could hike in these things ). I am not a sneaker girl ( o.k. - middle-aged chick, really ).
I also like these

You could also revitalize your old ones. If they are leather, get some shoe polish, new laces ( maybe in gold or silver ).........if they are canvas scrub them with an old toothbrush.
With that said, I LOVE the Payless ones and they seem like a good stop gap measure while you are building you funds.
Hang in there. It is really tough having little ones and focusing everything on them.
If you need a pick me up maybe, instead of shoes, you could go to a movie by yourself or spend some time at the bookstore by yourself with a cup of coffee......
HUGS !!!!!
