Women’s Techsun™ Interchange 3 Sandal is rated 3.0 out of 5 by 6.
Rated 1 out of 5 by from Alas, not the sandal I expected Although I had ordered a size and a half larger than I usually take, there was something about these sandals that just did not fit. I adored my older pair - and although they have been through mountains and rivers from the Himalayas to Israel, they always felt comfortable and enjoyable on my foot. These new pair are made in Vietnam [instead of China], look similar but have absolutely no bounce, arch, or cushion in the soles and were not comfortable to my foot. How I wish they would bring back the former hiking sandals!

Rated 3 out of 5 by from shoes I have an older pair of these shoes that's why I wanted another. The new pair is not made quite as well..... It runs small around the foot, the bottom is not as thick therefore not as comfortable......Wish I could have gotten the same exact pair I had before!!!!!!!!!!!

Rated 4 out of 5 by from Nice sandals Although these sandals are a bit thin with minimal cushioning, they are cute and functional. It's awesome that you can wear them as a true sandal or a slide sandal. I wore them hiking for the first time and they were comfortable enough. Only got 1 small blister where the sandal rubbed on my ankle but that is to be expected when breaking in any sandal!

Rated 3 out of 5 by from Interchange - not as good as it used to be! The shoes were too small; I will return them. (UPS wants over $14 to return them; will check the post office.) The old Interchange shoes were fabulous! I had 6 pair over the years and loved them; wore them all out. Wish I had ordered several extra pair back then. I don't think the new Interchange III is as good a shoe. I MAY reorder a pair in a larger size thou, to see if I can get a good-fit. Depends on what it costs me to return the pair that doesn't fit.

Rated 3 out of 5 by from Too Small I loved everything about this sandal except that the sizing was too small. I have an old pair of Columbia sandals similar to these and loved them. I was replacing them because I've had them for 5 years and they are worn out. I ordered the same size as all of my other shoes and they were about 2 sizes too small.
