People with medium-sized heel, mid-foot and forefoot can use the Nike LunarGlide. This running shoe can surely give a great fit for those people. You will be assured that you will really feel comfortable while running. However, for those people who have wide feet, this may not be a good choice. If you really want to experience unmatched fit, you can look for other running shoes that have available wide sizes.
In terms of the size of the shoe, it follows the standard running shoe length. This means that in order for you to get the perfect fit, you only have to get your actual size. Unlike other running shoes, there is no need for you to get half size bigger or smaller than your normal shoe size that is why it does not really create confusion.
