I bought these shoes (the color in the picture is green and purple - although the ones I ordered were supposed to be black and pink) because I for I'm training for a marathon and I need a second pair, the same as the ones I train in (which I bought directly from Nike and are shown in black and white in the photos). I put a pair of shoes side by side and to my surprise the pair I received from this seller at Revain is missing the Nike logo on the back, the sole has a different logo (my current shoes have a tick). , although it becomes visible with wear) and unknown symbols on the valve instead of the Nike logo. I could have hurt myself walking in those wrong shoes. These shoes may be unsafe and this seller should be removed from Revain.
