Nike is no stranger to creating shoes that are both functional, as well as fashionable. At first glance, the Nike Free RN CMTR may look like another minimalist model, the Nike Roshe Run, but the two shoes are very different. The Nike Free run line is aimed at being what a minimalist running shoe should be, trimming the excess fat while still leaving the core running fundamental features that runners seek in a shoe. The second half of the name, RN CMTR, stands for "run commuter," with the vowels strategically removed to shorten the overall name of the shoe while still effectively alluding to the capabilities of the shoe. This shoe was intended for light competitive purposes, performing it's best when being used to run in a straight line. Nike's goal for this shoe was to create a comfortable shoe that was cost-effective and efficient. Depending on your needs, this shoe will either fall under the category of being exactly what you want in a shoe or exactly what you don't need.
In an effort to be as concise as possible, the entire outsole is basically an extension of the midsole with a few minimal additions such as the rubberized pads that provide some traction. The areas that Nike chose to place the rubberized pads are in areas that typically see the most amount of wear on an average running shoe. This inherently enhances the durability of the outsole.
The midsole and the outsole are one cohesive unit. Due to the actual absence of a separate material that would compose an outsole, the midsole foam makes up almost the entirety of the outsole, except for rubberized pads placed in the toe and heel region. Deep slotted grooves can be found in the foam material midsole that allows for better flexibility.
This shoe is not recommended to runners with overpronation or supination, because the adjustments the shoe makes to assist both running styles are nonexistent. These shoes are recommended for runners who need an inexpensive shoe to run straightforward competitions with, not competitive events that require more movement outside of casually running in a straight line.
