Rated 1 out of 5 by from Not the usual Columbia quality Wore these flips maybe 3 or 4 times and they are ruined. The piece between the toes "blew out". Not what I expected from a Columbia product.

Rated 2 out of 5 by from 5th pair that strap broke between toes These flip flops are nice when working. The strap between the toe breaks very easily. I have had 5 (FIVE!) pairs fail due to the strap breaking just for normal wear at the coast, getting in and out of boat, slippery decks, etc. The good news is Columbia stands by their product and has replace all 5 pairs. Maybe one day they will correct the problem. They fit nice and are very comfortable, but the toe strap just sucks.

Rated 1 out of 5 by from A bad choice for Hawaii I purchased these for a recent trip to the Big Island. It was a terrible choice. After two days of cuts and abrasions due to poor design, I switched to flip-flops.

Rated 5 out of 5 by from MEN'S TECHSUN™ VENT FLIP LEATHER PFG Got these to wear in the boat and around the house & dock. Had about a month and they are perfect for me. Good snug fit on the feet and good traction on a wet boat and/or dock. Thinking of getting another pair, just for back up. (I have family members who have been known to "borrow" for days at a time.)

Rated 3 out of 5 by from Flip flops This is the 3rd pair of flip flops I have purchased for my son in the past couple of months. The first pair broke at the toe hold within 2 months. He loved them so much we ordered another pair. The 1st day he wore the 2nd pair they broke at the toe hold within the first couple of hours of wear. I contacted Columbia and was pleased to know that they do stand behind their products and warranty footwear for 1 year. I ordered yet another pair and have returned the 2 broken pair. Can't comment on warranty process as of yet because I just returned shoes a couple of days ago.

Rated 5 out of 5 by from Great flip flop! Made Tough! I admittedly am very hard on sandals. This flip flop has seen beaches in Florida and seen mountain tops. Fit and feel is fantastic.

Rated 1 out of 5 by from Be Careful With Vent Flip Design! This was going to be my third pair of Columbia flips. I've had a pair of Techsun Flip III for a couple of years, wearing them a lot, and they've gotten a bit flat. I bought a pair of Techsun Vent FishFlip PFG's and they are great - a thicker very comfortable footbed, great fit and feel. I wanted to replace the darker Flip III with a pair similar to the FishFlip, so chose these, not noticing the different toe piece. Big mistake. The Leather PFG doesn't have the soft nylon toe piece, and the leather part was brought under the straps and sewn, creating a very uncomfortable raised, rough section. (See photo below) It rubbed my foot raw in a very short time. They are going back. The photos below show the different designs. The first photo shows the Flip III nylon toe piece, the second the FishFlip. The third and fourth photos show the leather toe piece on the Vent Flip Leather PFG. Go with the nylon toe piece!

Rated 2 out of 5 by from Toe strap binds Overall quality reasonable but fit and function were poor. Tried for 1 wk to break them in, but the strap was too tight and binding over top of the foot. Avoid

Rated 5 out of 5 by from These are great I wear these shoes 3-4 days a week in the summer. I have several pair. They outperform all of the other flip flops I have bought. I usually go through about a pair per season. I wear a 12 in dress shoes, 13 in tennis shoes and 14 in these flip flops.

Rated 5 out of 5 by from Highly recommended Excellent quality product as you would expect from a Columbia product. Color is the best part as it blends in easily with the dirt - so less frequent washing ;-) Highly recommended!

Rated 4 out of 5 by from Men's Techsu Vent Flip Leather PFG Living in Miami, Florida and on the waters or outdoors 30-50 hours a week has proved to be a great way to review these products. The Techsu is relatively lite, fits true to size & easy to clean. The vents are a great idea. Hopefully more colors will be available & improvement on the bottom threads would be very nice. They grip well but would like to see them last longer. Other than that, good flips!

Rated 4 out of 5 by from Runs large I have Columbia hiking boots that are a size 13 so I figured it was a no brainer to order these in the same size. They run an inch longer than expected so they fit like a 14. The quality of the flip flop is just fine and I like the fact that it runs a bit narrow because I'm a B width. I will return for a size down and hope that works.
