SkechersMen's Afterburn Memory-Foam Lace-up Sneaker

Q: Is this a good running shoe or meant more for daily, casual use?

I wear mine for work and casual, same as poster before me insoles wear out pretty quick great shoe though. I used waterproofing spray on mine and they don’t seem to get wet much.

Q: What does 10D M us mean also 10 4E us maen

10D M means the width is medium wide. 10 4E means the width is much wider. I have a wide foot so I get a 4E width shoe. You can go to a shoe store and have you foot measured so you know the length and width of your foot. For a 10D M the length is size 10 with a medium width.

Q: How much bigger is the XW width compared to the M?

I am a size 12 and have a wide foot so got the XW in that size. Shoe was too long, could have gone with a 11.5. And it was WAY too wide for my foot. Could have easily gone with M width.
