After carefully following the sizing instructions on their website, I ordered a 39 ( I typically wear a 8.5-9 in US woman) in black high heel with covered toe. As everyone states, shipment was really fast, here within a week! Upon arrival, I couldn’t wait to try on my new clogs, but I was sorely disappointed when I found them to be way too small! Right then and there I re-measured my feet thinking I must have messed up, but no, the measurements were sound and I should be a 39. I’m assuming the inconsistency is because I have wider feet, so my advice is if you have wide feet, go a size up. The exchange process was a breeze, no questions asked, everyone in customer service was very helpful and willing to do what was needed. although I had to pay for the return shipment and they didn’t have a size 40 in the original shoe i bought, I am still very happy and giving them 5 stars.Because they were out of the Black I got my second choice, red highheel peep toe. I LOVE THEM!! I’m actually really happy I have these instead of the black ones, but I will be purchasing the black eventually too. I oiled the base with olive oil which brought out the gorgeous wood grains and darkened the wood slightly. I didn’t take a before oil photo, but I personally think the shoes look way more classy with the oil.I’ve been wearing them around the house for a few minutes on and off over the past couple days to slowly allow my feet to adjust, but I can already feel a difference with my arthritic toe. I’m a barefoot person, so if you’re like me, clogs are not the shoe to put on and walk around town when you first get them. Your foot and leg muscles need to learn and adjust to the roll and lack of foot movement. With patience and time these will be my go to shoe!!
