Fits big, and wider than they look in pics

I wear a US size 12.  Every single shoe I've bought in the last 20 years has been a size 12, including running shoes and formal shoes.  These, however, are really roomy.  I'm afraid of exchanging for the next size down since there are only wholes.  They are also really wide, more so than I expected.  The top down picture is at a slight angle so it hides the full width of the shoe, but it not clownish yet....almost though.  I got a great deal and so I'm sure if I will return them or not, especially since the quality looks good for the price, and they look like they would do well over the winter.

Ordered wide, but their wide and my wide, are somewhat different.

They do run larger than expected. I looked at other reviews before ordering so I bought my usual dress show size of 6 instead of usual boot size of at least 6 1/2 but they are still looser than I normally like my boots to fit. There was also a stitch that's a little loose that I think I can hand tighten. That being said, they are beautiful and I will be wearing them out tonight.

Turned out to be larger than I expected, but decided to keep them and see if they will shrink a little after wash.

The legs of these jeans, although straight, are much wider at bottom than they appear in the picture.  It is unfortunate because otherwise the jeans fit really, really well.

Ordered a large after looking at some reviews (I'm a size 4-6 in USA clothing) and they fit well, only the bands on the side are way larger in width than they appear in the photos.

I love these shoes, but they look HUGE on me. I wore them once and a few people pointed out how they look like zombie stompers, it was then I realized I should have gone a size down. Since I wore them, I cant return them, so I have dedicated them to my concert shoes.

Somewhat large, but still super cute and comfy

Fits very large...unlike other Mark Nason boots that I own

I like them overall, but my foot looks a little wide in them, because the base of the shoe is wider than it looks in the pictures.  I thought that I could possible wear them with cute white pants/capris and dress them up a little, but now that I have them, and because they look wide, they seem more casual.

I wear a ladies' size 9 and the size large was too big.  They are wide, maybe because they are unisex.  Exchanged for a medium and am keeping those.  Photos are of the large size.

They are really warm.  Plus, they seem to have a better padded insole than some others I tried.  No support, but a good pad to walk on.  I like that they come up well over my ankle and keep it warm.  They are a little bulky to walk around in, so I wear them mostly while watching TV.

In real, they're not so cute like on the picture, but warm and cozy (will fit more for someone with wide feet)

Bigger than expected, but hell, they look like moccasins.

Got these in a wide for my 4E feet. They run about 1/2 size bigger, but expected that from Clark and ordered 1/2 size smaller than normal, which was the right size.
They are wide all around, not just in the ball of the foot. For my duck shaped feet (wide ball, narrow heel) this makes them too wide in the heel. Stick-on inserts solved that problem.
They are well made and after solving the fit issues, comfortable.

These look really nice and they are fairly roomy.  My foot runs at the max of wide width, so the little toe is still very, very slightly scrunched.  I can spread all toes out if I make an effort, though.  The heel has more room than it needs, but the aren't moving up and down as I walk.  The big toe has more room than it needs, especially to the side away from the other toes, which is really odd.  Who has feet that curve like that?

I like the fit of these so much that I'm going to try to find some others that are similar, just look a little different with stitching or something, so I'm not wearing the same pair every day.

The only reason I gave four stars instead of five is because of how confusing the information is regarding sizing.  The chart listed in the photos imply the shoes run larger than standard (US), but the reviews are mixed - seemingly based on when the shoes were ordered, as the makers seem to have altered the sizing of the shoes at some point, and different designs in the same style are reviewed inconsistently.

I ordered these in 8, my usual size being somewhere between 7.5 and 8.  They were too large - not exceedingly, but enough that I would need to add an insole or padding and/or wear them with thick tights or socks.  The width was more generous than in most heels I have tried on - and having a wide, flat foot, this was pleasing to me.

The shoes themselves are incredibly comfortable.  Since they do not have platforms, they still need to be treated like high heels when walking, but I did not feel any of the usual pain or discomfort of heels when trying them on.  The shoes are extremely cute and well-made.  They even come with a spare set of heel soles, which goes above and beyond what you would expect from a shoe at this price point.

The only other (minor) issue I have is that this particular print (Geometric) was a bit off in color compared to the photographs, but such can be expected when viewing products on computer monitors.  I was expecting the yellow to be more pure, when there is a slightly stronger neon green hue than what is visible in the photos.

Overall, I am very happy with the shoes, but I will be returning them with the intention of ordering a size down in a different print.
