SIDI Fusion Lei Women's Boots 4.6 5 31 31
Great price for great product! I am very happy with this boot, theres not really airflow as that isnt what its made for, it has held up through many many long rides, a few hikes at the end of a ride when we stopped, and once i even forgot to take my shoes to work and had to work an 18 hour shift in these, my only single complaint would be that it is narrow, but thats not really their fault that i have wide truckasaurus feet for a female. fit mostly as expected, dont be discouraged if they feel small at first, they stretch out a bit to fit your foot best, all around great product that I have not once regretted purchasing.

Wide foot and heel bed I ordered a size 42 as I wear a women's size 9.5 in the USA. I have a long narrow foot and learned that the SIDI brand probably isn't the right fit for my foot. The boot was slightly too small with my large toe pressing against the front of the boot. The boot was very wide for me around the arch and heel of my foot and I was able to freely lift my heel several inches in the boot. I was super disappointed as I really love the style and safety features of this boot. I also found the calf circumference large, but there are velcro straps that could allow you to tighten the circumference. These boots feel really solid. The heel, toe box and ankle protection seem excellent. I really like the look of the boot as well and if you have slightly wider feet this may be a great boot for you! If you have long narrow feet like me, this may not be the brand for you. I ordered the Dianese Nexus after speaking to the RevZilla reps as they said their boots tend to run more narrow. Hope this helps! April 27, 2016
SIDI Fusion Lei Women's Boots Great boot. Fit and finish are excellent. Good buy for the money. April 26, 2016
Highly Recommend the SIDI Fusion Lei Women's Boots These boots are great, and you can't beat the price! Everything you want from a motorcycle boot. Fits great, allows for movement (without having to be broken in!), looks sharp, all the right safety features and comfortable on and off the bike. I would highly recommend these boots. I am a true 8.5 - I ordered the 8.5/41 boot and they fit just right. I got them in white/black - they look awesome and go in well with my white & blue accented gear. Buy them, you won't be disappointed! April 26, 2016
great boots overall boots are really stiff when you get them. Need a bit of breaking in. They are true to size (the size listed under sizing) so dont make the same mistake i did reading a review saying they are too big.. April 7, 2016
Great quality boot Overall ,great looking boot, protection, just need broken into... March 15, 2016
Nice boot, too large I purchased these boots because I was looking for an armored boot for track days. I wear US women's size 7-7.5 shoes, and bought these in a size 39. According to the size chart, this should have been a perfect fit. However, when I received them they were too big for me. I ended up giving them to my sister who has a size 8 foot and they fit her perfectly. That being said, they are stylish and attractive. February 5, 2016
Solid daily casual boot. Nice white leather. I've put about 1,900 miles on these boots so far and they are awesome. My commute to school is blessed with some Pennsylvania twisties, and these boots stay gripped and balanced on my pegs so well that my foot position isn't even a thought. The pucks are changeable if damaged and the white leather stays really clean. My group has a pair of eight-year-old SIDI men's boots that get handed down to new riders and besides a little leather damage at the toe, they look amazing. The plastics at the toe of the Fusion Lei are placed for maximum friction protection, so if you have a habit of dragging your toe at take off or at stops, you will be damaging the plastic and not the leather. I sometimes drag my heels at an easy stop, and the rubber sole has not even begun to change color. Shifting in these is a dream, after 100 miles I had it figured out. Air flow gets a bit sticky if you're over 80 degrees, but I wear running socks and my feet are fine. With a pair of heavy wool socks, these boots still fit and stay warm in 30 degree temps, and I run really cold. These boots will stretch a little, but I would go up a size if your toes are very cramped. I wear anything from a 7 to an 8 in American women's sizes, and I ordered a 39 after trying on the 40 at a local store and feeling like they were too big. The 39 fit perfectly. My feet are extremely narrow in size but expand towards the middle of the day, making many shoes uncomfortable, and I haven't had a problem with these boots. One note, if you order and the toe box is SORT of cramped while you are walking/standing, it will stretch and you likely won't notice on the bike. You will have to have slender calves, so if you are unable to zip up a mid-calf casual boot I would not recommend these boots. I recently went to the Revzilla headquarters and tried on a few pairs of women's pants, these boots fit under everything like a glove. They fit over skinny jeans with layers. Hiding these boots under pants feels like I'm somehow cheating on my gear because they're so pretty. My decision was between this boot and the more aggressive and more ankle-stable SIDI Vertigo Lei. The Vertigo has some of the best and most well placed protection on the women's boot market. My decision to go with the Fusion Lei is only because I commute to school and have to wear my boots all day. The Vertigo would have been my choice, based soley on their enhanced ankle protection, but they are simply not practical to be wearing around all day because they are just too stiff and they click. The ankle protection in the Fusion is built into the boot, so you will feel your ankle click into place, and I have no worry that my ankle will stay stable and in proper position in a down, and bonus: they look amazing in person. People at school compliment me on them all the time lol. I haven't ridden two up in these yet, but I don't think you'd have a problem and they would probably be one of the best pillion rider boots available. As for comfort, I just rode in these from 7am to 7pm, realized I forgot my casual shoes, and ended up wearing these out to a Latin club for four hours and dancing all night. They are made to balance so well that I could pretend I was wearing heels all night anyhow. That's why I'm currently hung over and writing this review, because my feet are only sort of sore, but these boots allow you enough top toe box room to put in a foot bed, so it won't happen again. Thank you SIDI. October 25, 2015
