Fits size 9 no problem, would be perfect for spring/summer/fall, but get something thicker for winter
340479
Nice socks for work. They're a little thinner than I expected -- which will be fine for spring/summer/fall, but sometimes they're not quite warm enough for winter. I wear a size 9, and the socks still feel plenty roomy. They would probably be too big for someone who wears sizes 5-7. They would probably fit fine for size 10. I got solid black socks with colored heels/toes -- socks with all-over colored patterns might fit tighter than what I got.

These boots are incredibly cute and seem to be of great quality (though I have yet to wear them outside of the house, so my review could change later). I typically wear a size 9.5 (very occasionally a 9) and have relatively wide feet. Because these do not come in a 9.5, I decided to order the 9. I'm glad I ordered down rather than up, because the 9 is actually slightly too large, leaving extra space inside and around the ankles, and causing the boot to slip up and down just a bit when I walk. It's only a small amount of slippage, though, and I didn't want to worry about reordering an 8.5 and risk them being too small. With thick socks, the 9 fits perfectly, with regular socks or none they're a little too large, like I said. I decided to give these boots 4 stars for this reason, because I'm not going to wear thick socks outside of winter; fall and summer in Indiana are far too humid for that. Otherwise, these boots look fantastic!

This is a review for the women's Ugg Seldon Boot, size 9 B or medium width, in the stout (brown) color.  I am 5'6" and @ 125 lbs with calves 13.5".  The boots leave a comfortable width at the top for skinny jeans or leggings, and are not near as wide as I feared from the pictures.  If your calves are 14.5" or larger, I expect they might be a bit too snug if trying to tuck jeans in.  The toe box is plenty roomy - I tried them on with thinnish socks but not dress sock thin - and I do not have narrow feet in the forefoot.  However, I do have narrow heels and have a terrible time finding boots because my heel slips and causes great pain instantly in most brands.  The only boot brands I have found that work for me are Ugg and Earth.

This boot is made of a quality, heavy leather, that is lined for some warmth but is not the ugg fleece lining so it is suitable to wear in fall and early spring without getting too hot.  I don't find the leather 'stiff' as some have said, but then perhaps they are comparing to the traditional Ugg sheepskin/suede in which case almost anything is stiff in comparison :)  The leather appears to be heavily oiled or conditioned and the interior of the box was stained from the boots, so I would not wear with light colored clothing until they have 'dried out' a bit just to be sure there is no transfer to clothing.  Like I said, the interior is fully lined so no worries there, but if you brush one leg against another or cross your legs I could see some oil transferring from the exterior if not careful.

Regarding the zipper so often mentioned in reviews, I had trouble when putting the paper inserts back in and putting them back in the box for storage, but no trouble zipping up when on my leg.  I soon found that pressure on the zipper (from the inside pushing out) is what causes the problem.  So, if you have wider/thicker ankles or calves and the boots fit snug I think the zipper will be a bit of a hassle, but if they fit a bit loose on you like they do me, the zipper is smooth and no problem.  Also, the zipper does not particularly bother me in the ankle, but I can see how if you had thicker ankles it could be a problem area as the boot does seem to 'break' there as you walk.  I can feel it, but just barely, but if the boots were tighter on my ankles I think it wouldn't work as the pressure point would increase.

All in all, not my favorite Uggs, but I still like them - a nice, plain, classic style that seem well made, at a fair price, that I will keep.  I would have liked a taller shaft, but that is not the intended style of this boot.  I find this shaft an acceptable height - better than the 12" ones that seem to cut off your calf (visually) right at the thickest part and just look awkward.

Edit: I tried these on in a size one half smaller (8.5 vs the 9 that I bought) in a DSW store over the weekend just to see if I could go down a half size.  While the length was ok, the toe box felt narrower.  Oddly enough, it was more comfortable where it 'breaks' in back in the smaller size.  However, the zipper was really really tough on that pair, particularly around the heel area.  Not sure if it was due to the boot being a tiny bit snugger (not tight by any means) or if some of the zippers have defects or need lubrication.  Seems like it is hit or miss a bit as to if you get a decent zipper.

Was looking for some for a while but wanted to make sure they fit and where thick enough for my feet. They work prefect, I am a size 9  1/2 and I didn't have any issues.

Lovely print and fit (2X is spot on; I wear 18/20).  Fabric is not mind, so would not recommend for winter use, but they are perfect for summer wear.

These are good quality boots for sure. They have some cozy material on the inside which helps with warmth. I also like that they do not make your ankles seem super thin like other boots do to where the boot material folds all around the ankle.
Do go up at least half a size. I am a 7.5 and got these size 8 after looking at the reviews. I am wearing thin socks today and they fit comfortable- with a tiny bit more room for thicker socks if needed, but comfortable enough to wear with thinner ones. I am sure that once I wear them more, they will stretch a tad making it even easier to wear with thick (or still thin) socks.
I am giving them 4 stars because I do not like how the opening at the top does the following:
1. It goes all the way to the knee (I am 5.1). These boots are actually shorter on the back and longer on the front. This helps when bending the leg, but I don't like that the front part reaches all the way to my knee bone. If you are tall, these are your boots!
2. The opening also hangs to the left side of my calf, if looking at it from a front angle. It hugs the inside of my calf, but hangs on the outside- if that makes sense. Also, When looking at them while I am wearing them, and standing to the side (profile view) it is way more obvious that the calf opening is very big on me. I do have small calves, but most boots circle around my calf evenly, as opposed to hanging more to one side of the calf. If you have bigger calves, these boots are for you too! They also have a little bit of stretchy material  on the inside of the calf, which I most definitely don't need, but those with bigger calves would appreciate.
Regardless of the negatives, I am keeping them because I have a high regard for Clarks. They make good shoes, and the boots look and feel high quality.

These are excellent snow boots for a great price.

Sizing wise, I am usually a true 6.5. I ordered a HALF size up based on the reviews here, and got a 7. I found that I have plenty (almost too much, honestly) of room on the inside when wearing thin ankle socks, but the boots are still hard to get off due to the narrowness of the top portion. When it starts to get really cold, I should be able to put on thick winter socks without a problem. I will add that they are a bit heavy, but that should be expected with snow/waterproof boots.

Very pleased with these socks. I'm a size 9-9.5 and bought the S/M.  Perfect fit. Very stretchy and material is more comfortable than expected.  Would have easily give 5 stars but the sock is a little thin.  I wish there a little more bulk to it.  Ultimately though I would buy again.

Fits well all around, my calves are just big enough that I can barely zip a regular sized boot with jeans and it's uncomfortable to wear, these fit perfectly! I wear an 8 or 8.5 normally, got 8.5 but could prob get by with an 8, these will fit better with a thick sock. Not much for padding in the sole so I will prob add an insert since I have the extra room anyway. Color is great, looks just like the pic, leather is nice and soft.

THESE ARE THIN............as is noted by the "weight".  Great weight for late spring, early summer and early fall.  I'm 200 lbs gal  and ordered an XL.  It fits but will probably shrink up if washed in hot water and dried on HIGH HEAT.  I'm ordering more but will go XXL just to have a little more room in the chest area. For a guy, it's probably fine.
I bought these to wear when I work outside and don't care if I get paint, stain, dirt etc on it.  At these prices you cant go wrong. Also like it's TAG-LESS and won't rub your neck raw.

I wear shoe size 13 and can fit into these, for feet any larger it may be a problem. They seem to be well-manufactured, a bit on the thin side so probably better for spring and summer wear than for winter.

As usual with prAna products this pair of pants are awesome.  Very thin so not good for winter activity if you live in cold climates, but would be perfect for spring, summer and fall.  The fit is perfect for me, I'm 6'2" and 167 pounds and bought a 34 x 34.

They are thicker than I expected. They are probably a better option in the fall/winter. Not sure I want to wear them in the spring or summer.

Bought size larger for my 5 yr old. They will be perfect by winter. She is tall and slim for her age. Warn, soft fleecy inside and soft shell outside. Perfect for wearing over leggings . I have no hope of them staying clean and expect a rip or two on the shell but good for price.

Love them!  They are to thick for summer.  but will be perfect for winter!

I'm a size 10, and these fit really well.  They're cute, and really rather comfortable.  They are kind of cheap, and now that I've been wearing them daily for almost a month, I can occasionally hear a *PIFF* of air coming from the heel on the right one.  However, I don't see any signs of them falling apart in the near future. There is also a really nice zipper on the side for quick putting them on.

However!  If these are intended for winter use (or, you just life in a place that it snows a lot), these don't have any treads on the bottom.  The front part of the sole is covered in a sort of felt-ish material, and is a little slippery on smooth surfaces, like icy patches or linoleum flooring.  The heel IS made of rubber, though, and provides more traction.

All-in-all, I think this is a very good deal.  I can wear them for long periods of time, and not have problems.

I purchased these for my son, but his foot was too thick, and couldn't get them on, but my daughter can wear them this coming winter, just hope the snow isn't too deep.  The appear to be warm, so I think they will do just fine.
