Rated 5 out of 5 by Best flipflop you can get! I love these, it's my 3rd pair. I am usually a size 10 fo flipflops but when i get these they are really tight, like cut off my circulation tight. But after about 2 days of wearing them the sole starts compressing and forming to your foot and then they are perfect! November 22, 2015
Rated 1 out of 5 by Too small, too tight, too narrow This is my second pair of men's techsun vent flip sandals size 14. First pair was perfect in size, comfort and functionality. Was sad when they failed after one season of daily use but I loved them and could not wait to order a new pair. New pair (same make, model, size and design) was a big disappointment; they said size 14 but were way too small, too tight, and too narrow. So much for consistency when it comes to quality control. Experienced no problem returning them and getting a full refund though I did have to pay for return shipping; that is I ended up paying $6.00 for the privilege of trying on a pair of sandals only to be met with disappointment.

Rated 1 out of 5 by flip flops I bought these flip flops a little over a month ago and they are falling apart. The rubber on the bottom is peeling off, and what goes over your foot has already ripped off. August 30, 2015
Rated 5 out of 5 by techsun vent flip sandles Had a weird fit from other sandles I'm used too. The front of the shoes was a lot further than my toes however the 1st time i wore them i was thankful for that feature cause i would of stumped my toes but the extra length in the sandle prevented that. Real comfortable on the boat with NO slipping. 7 hrs. On the water and my feet didn't hurt for once August 24, 2015
Rated 5 out of 5 by Excellent Product Let me start by saying I bought a pair of Columbia Techlite flips in Estes Park, Co while on a trip with our grandchildren when they were young. I bought them because they felt so good the minute I stepped into them. Now the grandkids are married with their own children and the flips look so rough I only wear them to the garden. The Techsun were just as comfortable when I tried them on. I expect them to last just as long as the Techlite. As for the Techsuns as long as the goop holds they may last another decade in the garden. June 12, 2015
Rated 5 out of 5 by I HAVE TWO PAIR!!! Stylish, durable and comfortable. This is my second pair and I love them. I still have the first pair and they look and wear as good as the day I got them around a year ago. Both pair felt a little snug when I first put the on but they stretched to fit PERFECTLY after wearing the around the house only a few of times. Now I'm waiting for Columbia to come out with a Vivid Blue, Autzen pair. When I'm not working, I'm in shorts and flip flops. May 17, 2015
Rated 5 out of 5 by Great product Great style and functionality. Comfortable sandals that you can wear all day long. I wear mine everyday and most of the time I'm on a boat. Not slippery when wet, great bottom grip even on a slippery boat deck, and doesn't leave marks on the boat. I have been looking for a long time for a sandle that can hold up to everyday use and I think I'm done looking. April 30, 2015
Rated 1 out of 5 by Poor Strap Design The sandal itself is well built, but the strap digs into the upper part of your foot after wearing it a small amount of time. I had to throw them out and buy something else. The sandals were killing my feet. If the straps were cushioned instead of having a line in them, then the feel would be fine. April 28, 2015
Rated 4 out of 5 by Great feel These shoes have great traction and are very comfortable for longer walks. My only issue is the sizing is a little bit off. I usually were a 8.5 US so I order a size 8. My toes fit exactly where the webbing is but there is still a good inch of shoe sticking out the front. I've caught it a couple times already. April 21, 2015
Rated 4 out of 5 by Nice Flippers! I like these flippers alot, but there is one this just a little weird about them. The heel side of the sandal is almost flush with my heel, whereas the toe side has way more room than necessary. Wish I could steal a half inch off the front and stick it on the back...then the length would be perfect! The rest of the fit is spot on, plenty of room with my foot under the strap, and the width is perfect. The tread on the bottom is awesome for a sandal, and the techlite makes these very travel friendly. With a minor adjustment these would be perfect! January 28, 2015
Rated 5 out of 5 by Great choice! I decided to buy new sandals for myself. I need durable and light flip-flops for the summer. I found this nice pair of sandals Columbia Techsun™ Vent Flip, but after I read some reviews I changed my mind and decided to buy another pair of sandals from Columbia, and found Tango™ Sandal that are durable and look nice on the picture. I have also read almost all reviews that were positive and decided to order Tango Sandals. When they arrived I was disappointed a bit. I found that they were too heavy for me. When I tried to walk wearing them, the heel of the sandals was dragging on the floor. It was uncomfortable to walk in these heavy clogs around the house. And they also looked old fashioned. I returned them immediately. After that I ordered Techsun™ Vent Flip and I was so much surprised that they fit my feet perfectly. The quality is the best, and their modern style is wonderful. They are durable and my feet feel comfortable when I walk in them. No dragging! The size is right! I think Columbia put thong strap a little bit back because the sole can protect your toes from hitting on cobles and if you decide to wear them on a wet weather condition the tight string will hold your feet and you will never loose them. I would definitely recommend them in spite of the fact that they made it from the synthetic materials. December 11, 2014
Rated 2 out of 5 by Good Size but wrong desing the size is good but the string that hold your foot are tight your foot must be really flat to use this sandals also the desing is worng toes remain to back don't looks good November 12, 2014
Rated 1 out of 5 by Bad Choice These are the most uncomfortable sandals I have ever worn. The thong strap is located too far back, and does not fit right. This is a major design flaw. I would not recommend these to anyone. August 1, 2014
Rated 5 out of 5 by Men's Techsun™ Vent Flip review These shoes are well made with good strong fabrics and supportive soles. They grip well through wet areas both on the ground and with your feet in them. The leather toe strap does not rub and is attached well to the sole. I have a bad back and the support these shoes gives is nothing like I have ever gotten from a flip. These are an outstanding shoe if they cost $100 but they don't cost that much which makes them an unbelievable value. Wear them once and you will be sold - get a pair (or two) today, your feet and back will feel so much better! July 27, 2014
