Can I Return shoe to exchange for a wider shoe?

I purchased a pair of FitVille Extra Wide Walking Shoes for men Wide Width Sneakers for Flat Feet Size 10.5 Wide. I received a size 9.5. I returned the shoes and requested an exchange. I was told that the return was received and they will send a refund. I have not received a refund nor I have I received the shoes in the size that I originally requested. So after approximately a month I have not received the shoes in the size I requested and so far I have not received a refund of the money that I paid for the shoes.

What is the heel differential?

If you are asking the height of the heel it is 1" These shoes have plenty of support for your feet and very comfortable to walk it, too.

I really need the the right size shoe i got two pair now that are the wrong size. I guess o just dont under stand this shoe sizing

Your question is vague. There are multiple sizes and multiple widths. What sizes and what widths did you order? Is it the same for both feet? What size do you usually take? The footbed is quite different for this shoe. Your toes are given much more room than other designs. I much prefer it. The pair I got was an 8.5 men's wide and they fit quite well. The heel is snug and supportive and the extra width give your toes a more natural feeling- they don't get squashed.
