I ordered a size 10 wide. in heels I always do a 10 even though I am a 9.5 in sneakers but heels. I never want my heels to fall off in the back. this is a true wide. I have wide feet. I am 5”5 and 167lbs. heels can be super tight and uncomfortable on wide feet but these I can wear all night . the plastic part doesn’t dig in your skin and there is like a cushion in the shoe that makes it soft!! love love love. got them for my Miami trip!
