will these shoes stretch as i wear them? i had to go a full size down to keep them on my feet and they are TIGHT... i HAD to have them, but im worried i wont get the use out of them that i want to bc of the tight fit. anyone else who owns these - did they stretch and give a little at all? also, did the decal on the top loosen at all or did it remain tightly sewn on? THANK YOU!!!
