Reebok Nano X2 Les Mills Edition

Women's size 9, but I wear a 9 and these are too big. Would fit better on a 9.5 imo but see Reebok size chart. Literally wore them AT MOST 7 times (crossfit is only an hour long) inside the gym only (except 2 times I tried to run in them on our track, 200 meters the first time and 400 meters the 2nd time. I remember because I got awful shin splints due them being too big) they are a little dirty from the gym floor because the floor is black rubber. I just paid $100 for them at the end of February. last photo shows after I wiped them off with just a wet cloth. I still have the box. Color is chalk (ivory), core black and power purple crosstrain training metcon lifting
