I ordered a US8 after measuring my feet. I have weird shaped feet. Very narrow heels, high arch, wide where toes join foot. I range from 7.5 to 9 in shoes. 7.5-8 in flip flops, 8.5-9 in athletic shoes, 9 in most boots, and between an 8 and 8.5 in dress shoes. I get blisters easily on my heels if the shoe is too loose so on dress shoes I go the smaller. I wear a compression sock all the time on my right foot due to multiple prior breaks causing swelling and my PF and heel spur.

These shoes fit me fine in size 8. Slightly tight but stays up on my heels correctly. They will give some over time making to toe box fit just a tad better. They have a great super low heel that are very easy to walk in.

I got these to wear to work and church.

My only complaint is they did not come in a box. I store my shoes in their box between use.
