Rated 4 out of 5 by Techsun II Mens sandal I wear a size 13 shoe, but needed a size 14 in this sandal. I also have wide feet, and the front strap has to be fully extended, where it shows mostly the black velcro. This is not very appealing, but the sandals did fit. It would be nice if the company would either make a "wide" extendable front piece or make the velcro the same color as the sandal. The soles are extremely comfortable, and seem like tennis shoe soles. Buy a size bigger than what you normally take, and if you need wide sandals, you will have to deal with the way the front velcro strap looks. Otherwise, they are good sandals and comfortable.

Rated 5 out of 5 by Hope this pair lasts longer I bought an earlier version of this shoe over a decade ago and loved them. Wore those sandals everywhere - beach, mountains, in water, even to Europe. When they wore out after more than ten years, I bought this version. It was just as great, but only lasted a couple of years until the bottom fell off one; the other was still like new. Since the shoe is so great, I have bought another pair and love them - perfect for water sports, the beach or just walking around. Curved fit is very comfortable. Easy to adjust for shape of foot. Can be as snug or loose as I like. These are really comfortable; I just hope this pair lasts longer than the last. April 22, 2015
Rated 5 out of 5 by Well designed lightweight sandals I bought these to replace similar Columbia sandals that I had worn out (because I really liked them). The new ones are just as comfortable, lightweight, and protect the feet well when walking on rough terrain. I think they are very good value for their price range. April 21, 2015
Rated 5 out of 5 by Very Comfortable These sandals are very comfortable and fit very nicely. I especially like the way the straps are wider so they slip out of the holder when they are taken off. February 17, 2015
Rated 5 out of 5 by Bahamas adventure I bought these sandals to wander around the Bahamas. They worked great on the beach or in town. The fit was good and they were comfortable. I wish the company stocked more of the black sandals. The company was out of stock, so I settled for a pair in quarry. October 23, 2013
Rated 1 out of 5 by nobody makes sandels which fit me the current generation columbia sandals are very poorly designed, the forward velcro straps are MUCH too short and do not fasten. Several years ago I bought a pair of columbia sandals which actually, fit, but those sandals are no longer manufacturerd. September 2, 2013
Rated 5 out of 5 by Favorite sandal After the 1st. time my husband bought this style of sandal he won't even look for anything else. His only complaint is that the Velcro wears outs before anything else. He wears them year around. Loves them and would recommend them. June 16, 2013
Rated 2 out of 5 by soles falling off The sandals are very comfortable .But after two seasons of kayaking the bottoms are falling off. I do kayak maybe 20 times a year. So i am very disappointed in these water sandals June 9, 2013
Rated 5 out of 5 by Good Value This is my second pair of sandals from Columbia and yes I do and have recommended this brand to my friends. June 8, 2013
Rated 5 out of 5 by Just Right Understand how a tall foot might be difficult to fasten the velcro but fastened just right for me. Easy on and off. Have put them through some tough wear and have stood up well. Not a flip flop wearer but these are just what I needed. May 20, 2013
Rated 4 out of 5 by A great pair of sandals I really like my new sandals. I saw in the reviews that they tend to run small size-wise so I ordered a size larger which worked out great. I would definitely order these again. They needed very little break-in time so you pretty much start feeling comfortable wearing them right away. April 27, 2013
Rated 5 out of 5 by Techsun III sandal These & their predecessor have been my "not at work" footwear of choice for 3 years. Light in weight, non-slip and superb grip on wet stones and sand. Comfortable as in forgetting they are on and easy to clean. February 18, 2013
Rated 5 out of 5 by tis product is great works great for launching my boat. I can walk right into the water and not worry about ruining them. October 16, 2012
Rated 5 out of 5 by Great product I ordered these on the recommendation of my cousin and I am glad I did. they fit and feel great the shipping was outstanding, I received them days before I expected them. Yes I would recommend these to others September 27, 2012
Rated 3 out of 5 by A drop from previous quality This is my second pair of the Men's Techsun III. I liked the first pair so well, I reordered when the old pair wore out. I like to stay with a good thing. I am living in Brazil so I had the shoes shipped to a friend in the US. He just brought them to me since he was travelling to Brazil. The straps on both the top and the toe area are so short they barely grab on to the velcro. I am not hopeful of long wear. I compared them to my previous pair and the straps are definitely an inch shorter. Probably a cost cutting move. Since I live in Brazil, I will not be able to return them. This is a drop from previous quality. JP September 27, 2012
Rated 3 out of 5 by Cost cutting too much I have been wearing these sandals for years. And I mean all year round since I live in Florida. I noticed that the area on the strap which has the velcro has been reduced. I have a high arch and when I secure the strap there is not enough velcro on the bottom part and because I can only get about 1/4 " to overlap the strap keeps coming loose. Looks like someone reduced the amount of velcro on the bottom strip to save cost, but for me it means not enough velcro overlap to secure the strap without coming loose. Will not buy another pair unless this is re engineered. September 22, 2012
Rated 5 out of 5 by Breaking in sandals This is my third Columbia sandal purchase. The sandals are always excellent and fit well and very comfortable, once they are broken in . Because they are made of rubber and ?plastic, they are a little stiff and slow to break in, but after a couple of days of wearing, they are fine! September 2, 2012
Rated 5 out of 5 by Second pair- best brand I've tried I wore my first pair for years. This was the closest model I could find to replace them and they're just as good so far. I'm not one for brand loyalty, but I'll definitely tick with Columbia for sandals. August 15, 2012
Rated 5 out of 5 by Best Sandal I bought a pair of these sandals 7 years ago and wore them out. My new pair is even better with some new high tech features such as the sure grip soles. These sandals are worth every penny I spent. August 11, 2012
Rated 3 out of 5 by Not as good as the last pair I had I have had another pair of Columbia sandals (the Wickiup?) for quite a number of years. I've been amazed at how durable they've been. The new pair I bought are smaller and not as heavily-constructed. I'm returning them because of fit, but I'll keep looking, rather than buying the next size up. Needless to say, I'm disappointed to have spent $22 in shipping (UPS charged $16 to ship them back) with nothing to show for it 3 weeks later. July 21, 2012
Rated 5 out of 5 by Great comfortable sandal I am a woman using the men's Techsun III because they fit & function better than a woman's sandal (& wider!). I just wish the velcro tab was a tad bit longer around the ankle - I guess I high a high instep. This is a VERY comfortable sandal & I wear them all day long at work-standing & walking alot. I will buy another pair of these any day of the week!! July 13, 2012
Rated 5 out of 5 by Comfortable Sandles True to size, smart in appearance, and very comfortale. Wore them during my vacation in Mexico and received many positive comments. I would recommend this type of Sandle to all. July 8, 2012
Rated 5 out of 5 by Third pair I have owned two previous pairs of Columbia sandals, both of which I wore daily until they wore out. This third pair seemed a bit stiff at first, but within a couple of days they felt as comfortable as the first two pairs, and they seem just as well made. I'm not sure what the little loop on the back is for, perhaps to hang them up, but it seems this feature could also cause the sandals to catch in certain environments. I wear them almost exclusively in the city, though, and for my use, they are perfect. June 27, 2012
Rated 3 out of 5 by Good for light use. I purchased a pair of these sandals about a year ago and at first they fit poorly but as with any shoe they eventually formed to my feet and became very comfortable. The sole has much more traction than an average sandal for this style. I never had trouble with chaffing from the straps. The only issue is that they cannot be abused. I waded about a mile up river in these while bass fishing. When I got home I realized that both soles had come halfway unglued from the foot pat. I assume the pressure from walking up river and constantly rubbing rocks loosened the glue. I did purchase another pair but do not intend on putting them through that much punishment and expecting to still have them at the end of the day. June 23, 2012
Rated 3 out of 5 by Product just okay 3 years ago i bought some Columbia "water sandals" much like these , they fit far better had a better "feel" and the soles were "vibram" ,they also had a pivot on the heel strap , which did break after 2 years ,however everything else about the old sandals was/is superior i have not been able to find them since , the fit on these is tight on the fron of my foot and the back strap rubs my fott on top . it seems like a quality build , but if i had tried them on first i would not have purchased . but that is expected when buying online April 14, 2012
Rated 4 out of 5 by Nice Sandals A very simple, nicely built, sandal. I am still "breaking them in" but if anything like my last pair - I'll have them for years to come. If I had to complain about anything - I would have liked the adjustable strap for the front of my foot to be a little larger (so I could loosen for more comfort). April 4, 2012
Rated 5 out of 5 by Comfortable!!!! Replacing 5 year old Columbias which were retired after years of salt water bonefishing and hard use. So comfortable, I hate to take them off. March 28, 2012
Rated 4 out of 5 by Techsum lll This is my second pair of sandle. I purchased this second pair because I was happy with my first pair. I really enjoyed the quality and comfort of my original pair. My feet are a bit thick and I find the staps are a bit too short. I would purchase them again if I needed another pair of sandles. March 28, 2012
Rated 5 out of 5 by Still the best I wore a previous pair of Techsun sandals constantly for a couple of years. I purchased this new pair of Techsun III since the previous pair were beginning to look a little worn. I have narrow feet but have no problems with the fit or comfort. Best sandal(s) I've ever owned. I were them to meetings, around the house and kayaking. March 6, 2012
Rated 4 out of 5 by The Sizing Has Changed, But Still Good Quality I was slightly disappointed after I received the shoes as the sizing has been reduced. This is the 2nd pair of size 15 Techsun sandals I've bought and when I match the new ones to the old ones sole to sole, there is a definitely difference in size. The result is that the new shoe is a bit of a tight fit when I wear them. Had I known about this, I wouldn't ordered size 16. Otherwise, it's a great shoe. February 4, 2012
