I recently bought a new pair of sketchers shape-ups. I love those shoes they are very comfortable and good looking. I stand on my feet all shift. I used said shoes one day but at the end of my shift I got a horrible sharp pain in my lower back I almost cry and it lasted for about 3 weeks. Has anyone experience this problem with this kind of shoes? Currently I am looking for the best shoes to work that do not bother my lower back. Thanks in advance.
