I normally wear Asics or Reebok.  These became available and I ordered them on VINE.  I ordered a 9 (only size available), but I wear an 8.  They only feel .25 sizes big and they feel tight.  Thus, you should order .75 sizes up and if you have a wide foot you will NOT like this shoe.

For example, you wear a 9 normally; you need to order a 9.75 or a 10 and you will feel about .25 inches too big which is fine since the shoe is so narrow that you will need the extra space.

As for the look of the shoe, the LIME GREEN heel makes you noticeable to cars and such but clashes with ANY outfit you wear that is not lime green, purple, gray, or black.

The shoe is very comfortable, but I don't feel any ankle support whatsoever.

The cheapest part of the shoe is the purple stripe on the sides; it literally looks like someone from an arts and crafts school put those purple stripes on the side of the shoe.
