I bought CL Pigalle Finzi (with lace like looking insert in the front) on sale. I am 7.5 in most shoes and bought 37.5. I tried 38 and I had a somewhat visible gap in the back and that's my pet peeve b/c I am afraid to slip out when walking (happened to me before). So the 37.5 feels kinda tight in the toe box, that is, my toes are hitting the sides of the shoe but the strange thing is that, they don't hurt at all like a shoe that's too small would. In fact, they are really comfy, yet I can definitely feel my toes snug against the shoe wall. I like this particular style and that they are not plain jane style. So my question is to the CL experts, will these shoes be actually ok to wear or will they hurt eventually? I have been walking on the carpet around the house and can't make up my mind. I also tried CL booties and the only size I could fit in was 38.5 and they actually appeared smaller than Pigalles! I can't seem to figure out these weird size variations in french shoes...Any input would be appreciated!
