Men’s Techsun™ Interchange III is rated 3.6 out of 5 by 16.
Rated 2 out of 5 by from Less forgiving than previous model In shoulder season, local stores didn't have stock; so I bought online, without trying the sandal on. Happily using a previous model, I went a size up because of the note about the snug fit (I normally wear an 8½). The pivoting back strap--the feature that attracted me the most--moves more stiffly, making the sandal less versatile. The straps bind more than the previous model, which was smaller; the back strap is of different design, apparently sturdier, but less giving. The sole is comfortable, but when I'm in motion, as in biking, the straps are not as comfortable as in the earlier model, which I plan to wear around the house as slippers, the back strap fraying away. Since the materials are synthetic, I do not expect the sandals to adjust to my feet. I will keep & use the new model, but will look elsewhere when it's time for replacement.

Rated 5 out of 5 by from VERSATILITY, COMFORT & EASE! Pirchased an earlier version of this "COLUMBIA" Sandal several years past; the overall quality of materials was good, and flipping the Heel-Guard up, or down was easy; nearly effortless. Accidentally stepped on the side of one a couple of months ago while rushing through the house, and my full weight combined with force of uplift, broke the tether. A good looking, very enjoyable, and practical design. Need more color arrangements... GBJ Silver Spring, Maryland - USA

Rated 3 out of 5 by from construction It was what I was looking for for a long time, however I was very disappointed that the moveable heel strap, for which I bought them in the first place, was not adjustable. When I move the heel strap up it makes the fit to tight for the width. Someone was not thinking wen they provided adjustment for 2 straps but not the third. If you could provide me with an adjustable heel strap it would make the sandal perfect, if not , I would caution anyone when asked about buying them.

Rated 5 out of 5 by from Fave Christmas Gift! This was the best gift to replace a well warn Columbia OMNI GRIP sandal. Needless to say my Husband is thrilled with them. Sometimes size 13's are hard to find. With the velcro closures it makes them easy to put on and off. They are now his most comfortable every day shoe. We live in Nevada so this is a great shoe for our casual lifestyle

Rated 5 out of 5 by from double order I love the sandals so will be keeping both pairs. By mistake I ordered 2 pair . Shouldn't your computer have a red light for a double order to the same address and check on it. To much hassle to return.

Rated 5 out of 5 by from Best Sandal Ever Created by Man I mean every word. I have owned every iteration of this Interchange Sandal, usually several pairs and they do keep getting better. The dual functionality of slide on and full walking sandal is brilliant. Light weight, comfortable, stylish and durable. Other than formal situations like work when I have to wear fully covered shoes, I am always on my Interchange sandals. Thank you Columbia for being awesome and I hope you continue to make this sandal until the end of time or the end of my days, whichever comes last. I have and do recommend this sandal to everyone.

Rated 1 out of 5 by from Wish the concept worked I have purchased this product twice hoping the fist issue was a fluke, it was not. The bottom of the first pair separated at the front. I thought maybe this was a poor manufactured shoe but I loved the versatality. I bought a second pair after first failure hoping the Columbia had fixed this failure, it has not. I just came back from a brief vacation in Maine where the bottom separated at the heal. Poor quality, I now have to find an alternative.

Rated 4 out of 5 by from mens techsun interchange III good product. well constructed. very comfortable as i live in florida and wear daily. i have had 2 pair of the old style and good results, this new style is good also but the new opening for the little toe is not needed and makes it less comfortable for me.

Rated 3 out of 5 by from Great Design and comfortable wear I have owned two pairs of those sandals. The sandals are comfortable to wear in many conditions. Love the Interchange design. However, the hinges break off easily. As this happened with each pair, I consider this a design defect and wished Columbia would improve on this particular performance aspect.

Rated 2 out of 5 by from Sandal blowout! The sandals fit good and were comfortable from the start. However, the plastic hinge pins for the heal straps are not strong enough. Two days into a salt water fly fishing trip to Mexico one of the hinge pins popped out. Had to sew the strap on with 60lb mono shock leader. The next day the other pin popped out. After sewing the straps on with the mono, I had no other problems. I suggest going with a different sandal or be sure to carry some heavy mono with you to sew them up when the hinge pins fail.

Rated 2 out of 5 by from Bring back the Titanium Thrasher This is the closest sandal I could find compared to the Titanium Thrasher Interchange. I have wide feet and to adjust the straps to fit my feet you can see alot of the velcro. When you flip the back up to wear as a slide it squeezes the top of my foot because the straps are bulky with the velcro. I am sending this sandal back I can not wear them comfortably. Please bring back the Titanium Thrasher Interchange sandal that was a perfect sandal. True to size especially for wide feet very easy interchange with no squeezing.

Rated 5 out of 5 by from Run Hermes Run! Wow! Unbelievably light and comfortable! I have narrow feet and have a difficult time finding sandals with enough of the hook & loop securing feature on the straps to fit my foot. Not these Babies. They secure with the entire strap! Another nice innovative feature is the heel cuff that flips up for a quick and convenient slip-on fit or flips down for a more secure fit around the heel for use on more rugged terrain. A truly great sandal for use anywhere.
