Rated 1 out of 5 by from These are not like previous Columbia sandals I have a watercraft and I use Columbia sandals all the time. After many years of using their sandals. This sandal is bad. You can not get it wet and walk in them unless they are strapped tightly. I have almost fallen several times because of these sandals. I told their customer service department about the issue, they said thanks for the input. I am serious do not get into water with these sandals, whether at a lake, ocean, or it's raining. They are not good in water at all.

Rated 4 out of 5 by from Straps Over all the sandals are pretty good, straps could be just a touch wider with a bit of padding for a bit more comfort like my old Columbia Sandals which these are replacing.

Rated 3 out of 5 by from Great to walk in Sandals are very light and pleasant to walk in. Only problem is that top strap is rather short so if you have a instep it really doesn't work well.

Rated 1 out of 5 by from Poor quality and comfort Not impressed. Straps are way too short and wire loopes are too flimsy. Pinched fit. Do not buy, I'm sending these back!

Rated 5 out of 5 by from Techsun Vent Sandal I order this EXACT same sandal every year to a year and a 1/2 as needed as I love them, I wear them each and everyday, as I work I walk a LOT everyday and (after initial "break in period") they are so comfy and last a long time and in my mind is a bargain! Living in The Keys with all the rain, they can get wet, they dry quickly, and no slippage, too! yeah, man, LOVE them!

Rated 3 out of 5 by from Product strap broke I liked this product. comfortable to wear but strap broke off under normal wear about one year after purchase.

Rated 2 out of 5 by from Wish these didn't hurt my feet. Like the look wish there were more colors. Left sandal fits and feels perfect. Right sandal fits but hurts my foot when I walk for a bit, not sure why but quit wearing them. Totally disappointed I've bought these sandals for years and never had an issue.

Rated 3 out of 5 by from the straps seem to be short Your product arrived in perfect condicions and in the correct size (8) I purchased. However, the straps seem to be short, because they doesn't fit securely and it releases the hoop-and-loop closure while walking, making it hard to walk with them. I'm enclosing a picture of the sttraps in use. Sincerley yours, Julio Fein

Rated 5 out of 5 by from grrreat This is the second pair I have purchased. The first pair I ordered the wrong size but I but I like them so much I wore them for the summer before I decided to order the correct size. The new ones fit right and I will keep them until they wear out. Donated the other to Goodwill as they were still in good shape in spite of my spring summer use.

Rated 5 out of 5 by from Big Foot likes these sandals. My husband wears a size 15 and it is very difficult for him to find sandals that fit and of good quality that don't cost an arm, leg, and a foot. I ordered him a pair for his birthday and he called and ordered 2 more pair because they fit and are of good quality for only $50.

Rated 5 out of 5 by from better than the rest bought these babies and wore them after paying. it feels so comfortable, soft. super flexible and fits well.. better than the other outdoor sandals that i had. definitely get another pair soon!

Rated 5 out of 5 by from Great Footwear Great footwear. They tolerate getting wet very well.

Rated 3 out of 5 by from Sandals My only basis for comparison for this sandal is 15 years of wearing TEVAs. There simply is no comparison. I bought these to get me through the remaining 2 months of the Kentucky summer. They will serve that purpose but nothing more. The sizing is true and they are attractive enough but not well made. Okay for the price.

Rated 5 out of 5 by from The best sandals ever I like Columbia sandals more than any other because they are light but strong, and their best feature is that they are ergonomically well designed.
Date published: 2015-08-13
Rated 4 out of 5 by from Won't let you down Worked outside all summer walking around in river mud, still wear these everyday and are just about good as new after you take a hose to them. Pretty stiff at first, takes some time to break in but once you do are very comfortable.

Rated 5 out of 5 by from A great Sandal for a big foot! I wear a size 17 shoe. I was very happy to be able to order a beach type sandal. It's much more comfortable then I could have imagined!

Rated 5 out of 5 by from Great shoe bought these for my husband for the lake. He loved them. They are very comfortable & durable for any type of water use.

Rated 3 out of 5 by from Rugged but somewhat uncomfortable Maybe it's too soon to review these because they might get more comfortable as I wear them longer. They're well made & water resistant but have many rough edges on the straps that rub on my feet. It's probably just a characteristic of the materials used to make them but I can't give a recommendation yet. I have a couple of other sandals, maybe not as rugged but a lot more comfortable!

Rated 5 out of 5 by from Columbia standard product Material Used Are So Good. It can be used for any type of functions. Looks wonderful on jeans.I have been using for 10 days & I don't have any complaints. It's 100% Waterproof

Rated 5 out of 5 by from Love'em! I bought these for a trip to Africa, and just received them. They feel and fit correctly and comfortably. I wear a size 9 shoe in everything I buy and these were no exception. They look great and fit my outdoor style pretty good. I love the drains on the sides and bottom for any type of water I may encounter...and I wanted these with the ankle strap as I have inverted my ankle on multiple occasions before and like to have a little extra support sometimes depending on the terrain i'm in. So that was a nice option to have. I also bought the regular flip-flop style version of this same sandal for more casual wear around the hut. They are equally nice! These are very lightweight and I expect them to last a while overseas, can't wait to put them to the test!

Rated 5 out of 5 by from Excellent, as always I have several Techsun sandals, but never before the Vent variant. They are always excellent, and this one is no exception. They are extremely durable, which is how I came to have several pairs. They are extremely comfortable. I like them because they are waterproof, light, fit well, and never wear out! And to me they look good. For me they fit true to size or even slightly large: I take 7 1/2 to 8 in a shoe, but the size 7 always fits perfectly in this sandal.

Rated 5 out of 5 by from Great pair of sandals Exactly as described. Happy with purchase. All great shoes take a while to break in (water helps).

Rated 4 out of 5 by from Good Waterproof Sandal I agree with the previous view that these sandals were uncomfortable at first...they definitely need to be broken in. This took just a day or two. Water drains quickly from these sandals. I purposely purchased these for doing some hiking in water, up river and waterfalls. The grip in water was really good. Didn't slip on wet rocks. They were perfect for what I needed them for.

Rated 3 out of 5 by from Not comfortable These sandals are quite uncomfortable on bare feet, okay with shorty socks, but who wears socks with sandals? The leather sandals are far more comfortable
