Hey! So i bought a pair of formal heels that are not too high. Probably only an inch or two. I bought the size 41. The salesperson wouldn't let me try walking in them for some reason i don't know. Once i got home, i tried walking in them and they keep coming off. I tried the gel inserts but to no use. I tried on size 40 in the store but it is tight on my feet. Especially because my left foot is slightly larger than my right. Pls help me!!
