Using the Skechers size chart, I ordered a 8.5, which is my usual size.  However, these shoes run small, both in length and in height at the arch. I trimmed the top of the shoe back (with a pair of scissors), which solved the problem of too tight over the arch of the foot, but they are still snug in the toe.  Later I bought another pair in a similar style in a size 9, and that pair fit better in length. However, neither pair has any arch support.  I bought these shoes for the comfort sole, which is a good feature.  However, I will not be buying any more Skechers.  For the price, I can get a better fitting and more comfortable pair of shoes in other brands.
