I tried these clogs on at the skechers store( size 6.5) and they were way too big. I normally wear a size 6.5. They had no smallers sizes in store, any other store, and none on their website. I found these on Amazon at $59.96 each so I played it safe and ordered a size 6 and a size 5.5. Still really big.  I am going to return them and order a size 5. The price I have to pay for a size 5 is $79.95..... Really? $20 more? Makes no sense. I have a knee implant that never healed and these shoes had the most cushion and didn't shock the knee so much. I'm on my feet at work all day and have gone through a bunch of different styles of Skechers work shoes and none of those styles felt this comfortable. It's ridiculous that I have to pay $20 more for an even smaller size. I hope the size 5 fits..... I'll update when i get them.
UPDATE:
Well I've had these for 6 weeks now. The size 5 fit ok but like others have stated, the inside of the shoe started sliding over making it very uncomfortable and the way the glue is on these, its impossible to put them back in place without tearing the bottoms. The toes on mine did cave in making it painful to wear as it dug into my big toe. Don't bother with these shoes, they are trash....80 bucks worth of trash. It's too late for me to return them and to make matters worse, I'm stuck with them til I can afford to get an entirely new pair of shoes. I am really disappointed with these. I've had several skechers work shoes but these are the worst. Had the tops of them not caved in and the inside of the shoe hadn't slid over these might have been ok but for $80 they should've held up.... Not failed miserably after a few weeks. Trust me.... There are a lot of reviews out there with the same problems. TRASH!!!
UPDATE #2:

Having missed my return window(5/26/2018) I called the Amazon customer service center and they were willing to take my shoes back and refund my $80 back to my account. 5 stars for Amazon customer service. Sub zero for the shoes.
