I wish sizing was mentioned, Large fits size 12 hiking boots best.

Great over boot, but I haven't tested it on slippery logs yet.  My concern is if the outersole is as good as an xtratuff chevron sole.  The sizing runs big for a large.  I chickened out on returning the large because of it being a bit too big and just ordered a medium as well.  The large is better for a person who wears a size 12 hiking boot, but it fits size 11-13.  I wish they advertised the sizing.  My medium hasn't arrived yet, but I hope it fits my size 10 tight.  Size 10 fits in a large, but there's like 1 1/2 - 2 inches of extra space.  Even with size 11 boots inside the large, there is still 1 inch of extra space.  But with some bulky size 11 hiking boots I'm sure the size large will fit good with little extra room.  Of course I bought this instead of xtratuff rubber boots for my occupation as an oyster farmer, because I'm super cheap.  With free shipping and heavy duty quality, its kinda hard to turn it down.  What I like best about over boots is you can backpack with them and carry breathable shoes.  These over boots are a bit heavy, but its because of the durability.  They do fold flat.  I'm giving 4 stars because the sizing is not mentioned.

I'm a size 11.5 in a good shoe, such as an Ecco, so even though some reviewers said the boots ran a little large I opted for a size 12.  When I ordered my Muckboots a few years ago they were also a bit large in a size 12, so I wear two pair of socks with them.  Other shoes I have, such as Nike sneakers are a size 12 and fit perfectly, and other shoes I wear are a size 13.  It's hit or miss with sizing.

I'd have to wear four pair of socks with these boots.  In hindsight a size 11 would likely have fit better.  I needed the boots now to do some cleanup work in the swampy part of our property, so I'm just dealing with the size, and with one pair of socks.  I'm not finding it that much of a problem.  If I had to work in them all day every day I would have returned them for a different size.

As others have mentioned, they have a really bad odor and should be left somewhere out of the house to outgas.  I leave mine on a screened porch.

I feel these boots are well designed.  There's a little ledge on the back you place your other foot on to help get the boot off.  The tops are plenty wide for me to keep my jeans comfortably tucked in.  And even though they're a size too large they stay on, even when walking in muck.  I walked out part way onto a beaver dam to remove some of it to lower the water level in the pond and never felt unstable, even when water began rushing around the boots.  They grip well.

Overall, I like these boots and would buy them again.  They are half the price of the Muckboot, a boot which develops difficult to repair cracks on the upper surface.  I knocked off one star for the horrible smell.  I would definitely buy them again but a size smaller.

Really good gloves, wish they had a size 12, but the size 10 works.

Could have used the XL size. I have a size 11 men's foot and the advertised size for the L was 9 -12.5.

I know I marked somewhat large, however for me, I have a very wide foot and for not being a "wide" size on the chart I find the room makes the boots more comfortable. Arrive quickly too.

Fits good with room to spare (6ft1, 180lbs, ordered a medium). Would be better if they fitted over ski boots

The quality of the boot is great. The leather is supple high grain. The sole has great tread and it is sewn (see the stiching on the bottom near the toe). Very comfortable except I would recommend ordering a half size up. I am 10.5D in every shoe I own. The 10.5D I ordered fits but is very snug. I could not fit a pair of thick hiking boots in this - thin socks at best.

5 stars for quality
4 for for sizing

4 overall.

I haven't hiked in them yet, but I'm normally between a 10.5 and 11.0 and the 12 fits me fine.  I got the 11 too but sent it back, too small.  I'll update after I try them out outdoors.

Usually a large will provide plenty of room for me.  But these run small.  I normally wear a size 14 and am a bit hippy.  These are tight, but because of the price, will keep and hope I ah-hem loose weight!

Very Sharp looking boots, well made.
A note on Sizing: I wear an 11 wide in tennis shoes and Merrell hiking boots.
10 wide is too small for me in Ariats and 10.5 wide is a little big. Maybe a 10.5 d (regular width) will be the perfect fit?
The wide do run very wide as it is a broad toe from my experience. Ariats seem very consistent in their sizing which is great.
I found Tony Lama to be very inconsistent with their sizing and Dan Post boots run almost a whole size too small.

Life is too short, buy the Boots !

I select the size that I normally wear but these boots came in a little large.

Like the boot, but wish they had 1/2 sizes. I usually wear 8 1/2, bought a 9 and it is super huge. I expected it to be a little big but I have on the thickest socks I own and still have lots of room for my foot to slide.

A durable boot that really was waterproof but the sizing is small. Bought them one size larger than I wear and were still to small. Should have gone two sizes larger. I work at a ski resort and wear these every day all winter long. These are the first boots since the old Canadian made Sorels that lasted more than one season.

I wear a size 10 so no surprise the large is a tad small. Otherwise I love them!

as a hiker, best to get boots 1 1/2 to 2 sizes larger than your regular shoe size----these were 2 sizes larger and have made a big difference---great support and very comfortable

Good thing I ordered big to accommodate thick wool socks.  A size 12 fits like an 11.  Quality is what you would expect from Sorel

I normally wear a size 9 in most shoes and boots.  I found the size 9 Targhee II uncomfortable after 1 hour of hiking because the boot was a little too short.  I'm now wearing a 91/2 Targhee II and am very happy with it.
