Product details

The Flexus Istra women's waterproof microsuede ankle boot combines cozy cold-weather protection with an easy casual silhouette. Soft waterproof microsuede is finished with a plush faux-fur collar, while two oversized buttons and stretch bungee-cord detailing add visual interest and help define the boot's relaxed winter look.

The faux-fur lining and covered insole create a warm interior feel, while the direct-injected polyurethane outsole is lightweight, flexible, slip resistant, and designed to absorb shock. A 1 1/4-inch heel and 1/2-inch platform keep the profile low and practical for everyday wear.

Narrow and rigid

I found these boots very uncomfortable. They're very narrow and the material has no give to it. They're very confining atop the foot as well. These may be OK for people with quite narrow feet, but would not advise for anyone else.

stiff

Even though I replaced the boot with a larger size , the toe is very stiff & hard. The replacement insole on one boot had a stiff wrinkle that can not be smoothed out. It was like it was worn or used before. I have several pairs of Spring Step shoes & have worn them for several years because they are comfortable. I will not be wearing these boots.

Poor quality and poor customer service :(

This is the second time I ordered it the first time the fit was poor - too small. Then when returned I was charged a fee to send it back. Second order defective shoe lacking insole - can feel grid of plastic sole through thin plastic. Called again and while the person on the phone finally did place a request for defective return, three days later STILL NO RETURN LABEL! Last purchase from Spring Step for me!

Inconsistent sizing & really flimsy material. Purchased my normal size & they’re too small. Why don’t brands use consistent sizing? So they can charge you a restocking fee when you have to return them and order another size. I returned the shoes & I was charged $7. I purchased these on sale for $49.95. When I tried to buy the larger size just now, the price increased by $10 from $49.95 yesterday to $59.95 today. And they have the nerve to charge $6 to replace the order in case it gets lost—and you’re supposed to get free returns. If buying an item is such a gamble that I have to pay $6 to make sure I receive my order, I’ll shop elsewhere. Fees as a tactic to increase revenue are pathetic. Provide a good product at a fair price w/good policies & you’ll have customers for life. I’m never buying anything from this desperate s**t show again. Enjoy my $7.00.

Runs very small

I am so disappointed because these boots are SO pretty and so lightweight, and even waterproof. But I ordered size 41 that I typically wear, and they were too small. Exchanged for a 42, and still too small, and they don't make a 43. If you wear a 10-10.5, these will be too small for you.

Perfect for winter

These are my new favorite winter shoes. They are comfortable and cute and warm. Even though they don’t have a zipper, they are really easy to pull on. I usually kick my shoes off as soon as I get home but these are so comfy I just forget I have them on

Excellent Boot!

Unfortunately the sizing did not accommodate my feet. I ordered a7, too small; returned for a size8! Too big. I was VERY disappointed as these boots are beautiful and I wanted a pair! Obviously, production in half sizes are in order…hopefully for next year’s inventory…

Love these boots!

Although I've only had occasion to wear these 2x now, these boots really lived up to expectation. They are waterproof, warm, and very comfortable to wear. Definitely recommend especially if you live somewhere cold and snowy during the winter (like the mid-west).
