SIDI Fusion Lei Women's Boots 4.6 5 32 32
Love these boots ! I'm a little person and bought a size 5.5---these boots fit beautifully ! Light and comfortable --- they are crazy light to walk in but study and stable. Great buy ! July 14, 2016
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
