I don't need arch support.  I'm flat footed.  We sell this brand at a store here in my town but I could never find my size.  So I ordered a Wide with.  I however have developed bunions on my feet and could not wear them even as a Wide width.  It felt as if they were squeezing pins and needles  across the top of my foot.  I gave them instead to my mother, who wears them quite comfortably.
