Great protection Great protection and a great look. A little stiff when walking around in them. Not great for wearing all day. July 26, 2016
Nice boot, sizing can be tricky! I purchased this as a gift for my girlfriend. I referenced the size charts when placing my order and raided her closet for shoe sizes. I still ordered a half size too big! Her main issue was the boot was tight down around her toes but she felt like her heel wasn't secure in the back of the shoe. After exchanging for the correct size the boot fits much better now however she feels the boot is still very tight around the ball of her foot. I wanted a boot with decent protection and she wanted a small fashionable boot. This product was the perfect compromise between the two. The hard parts are solid feeling and offer a decent level of protection. Where as the boot itself is small enough not to limit her range of motion and doesn't look like a full on race boot. Only real downside is the stiffness of the boot. I understand the boot must keep its shape to offer protection but the sole is extremely stiff. It is by no means a deal breaker but makes off the bike activities difficult. All in all a great boot priced reasonably that offers a solid mix of function and fashion. March 3, 2016
Worth the money! I have had problems in the past fitting a leather boot under my shifter, so I switched to more technical boots, which are not as tall in the toe area. This boot replaces another short boot that suffered toe-cap collapse on both boots. The toe protection here feels much more substantial. The air flow is good, and there seems to be a ton of protection. I will probably have my shoemaker glue a thin sole on to the bottom for more tread, and to make the boots last longer, as I wear these for travel, which involves walking around a lot. These seem plenty wide in the foot, even though billed as slightly narrower than standard. I'm not sure I love the silver accent, but the rest of the features are what I want. June 6, 2015
No good for large legs I've had a lot of trouble finding boots to protect my ankles because I apparently have freakishly large calves compared to whoever these boots were modeled around. I got these hoping they would fit since they didn't need to go over the calves. I was wrong. The didn't even zip up over my ankles. Very disappointing since these boots are well made, have lots of protection, and look great. The sole sizing was perfect, I just wish these weren't made for women with tiny bird bones. Hopefully a pair of men's boots will fit. June 1, 2015
This product looks a million. Great look, lot of features and after a while also very comfortable. April 13, 2015
Not Good for New Riders Bought these boots about a week ago and right out the box they are super stiff. I could not shift in these boots at all. I bought a regular pair of work boots (like construction boots) and was able to shift with no problem. So as a new rider i would not recommend buying these as your first pair or if you do just know it will take allot of effort learning how to shift in these boots. I will be using mines for when i do aggressive riding but just everyday commuting i will be using my work boots atleast til I get better at shifting January 23, 2015
Love this boot I've worn Sidi mid-calf boots for 8 years and was so excited when I saw Sidi had a short boot for women. This boot has not disappointed. It took about a week for the stiffness to go away and to get used to shifting ....but now it fits like a well worn glove. They are significantly cooler when riding on days when the temperatures are in the 90s+. Ankle is fully protected. I get a lot of compliments on them from non-riders. I even wear them if I am not riding! Happy, Happy July 22, 2014
Best Women's Low Riding Boot This is an awesome example of a low riding boot. It is very stylish, quality built, super features and the fit is just right. Two side air vents allow for ventilation on hot days. These boots will take you from zero to "go" in no time at all and they look awesome. July 21, 2014
