I ordered several pairs of wedge shoes from keds that are on sale and they feel tight in the toe and lose in the heel. My toe is right against the front of the shoe but my heel lifts out when I walk. I have narrow heels. I am trying to decide if I should order the next size and buy heel cups or something to make them fit or just send them all back? They are all quite cute and I think they'd be really comfy in the right size. What would you do?

Thanks,
Cosmo
