These are super light weight! They feel like air! There is plenty of space in the toe area, as well as full toe coverage and no pain along the sides of my feet. I am still recovering from two recent foot surgeries and I can say that my feet really are horrible, so buying shoes online is a long process for me because I read every review and try to match it to my own foot issues. I wear a size 10; I don't have particularly wide feet but sometimes one foot does swell. I bought these in a regular fit and they are just fine. I didn't require a wide at all. But again, I don't usually wear a W.
My feet do not bend because the bones have been fused to include the toes and other main joints. Standing on my feet is not fun for me - or even walking for long periods of time,  and sitting makes me swell too, but these were so nice to have for a change.  I so wish these shoes were a little prettier as they look more like suede and the plastic soles look like cheap scuffed plastic, but I can't complain for how soft the inside soles are. Because of my swelling I also wish the strap had a little more give to it, but it's still manageable for me. And the top of the shoe and the sides do not touch any of my sensitive scars so they really are a gem to wear. After only wearing them for one day in an office sitting at a desk for 8hrs, they already looked a little scuffed and worn, which is a negative.  But I work behind the scenes so beauty is not necessary - but comfort is. I love Merrels too, but these are such a great price that for right now if you have as many issues as I do, I would say do not hesitate to buy them. Also, they were almost $20 cheaper on Amazon than on Zappos right now, so that's a great deal.
