I received my Trek Sports in the mail today but I am kinda bummed because they are too small and I will have to return or exchange them. I ordered a M43 but they are definitely too small - my toes are practically curling up in the pockets.
I am pretty sure I wear a M43 in my KSOs but I am not certain because the part of the sole where the size is labeled has been worn out from use and thus is unreadable. So I was pretty much banking on memory that I am an M43 (I didn't measure my foot because I trust my memory) but maybe it is possible that I am wearing an M44 KSO. Regardless, I will be returning the Trek Sports I got today - at least CitySports makes the process easy!
So what is the material on the inside? Is it like the outside...or is it lined with a different "softer" material like the bikila?
Well I do not own the bikilas so I cannot really make a direct comparison but I tried to take a few pictures to put up here for you guys. BTW, I didn't realize that the size is labeled on the side of the shoe, I thought it was on the sole, and I just checked my KSO's and I am an M44. Doh!! It was my own dumb mistake getting the wrong size - oh well!
Also, I can say that it seems like the upper lining is what is touching your feet on the inside, similar to my KSO. Someone else maybe can chime in about that aspect too.
