SIDI Fusion Boots 4.5 5 57 57
Very nice boots! Exceptional boots for the price. After getting my Sidi Fusion pair of boots I wonder why it took me so long to buy them! Would recommend these to anyone looking to get a good pair of full sized boots for under $300. The style and protection of these boots are simply perfect. I love to wear them under my riding jeans. The boots are pretty tough, which is good in terms of protection but it takes some time and miles for the feet to get used to them. The boots are narrow and I strongly recommend to choose one size higher than usual. I wear 11 US / 45 EU shoes and I bought an 11.5 / 46 pair. Even buying one size higher, my feet suffered at first... Now, the fit is simply perfect! I love them! July 21, 2016
Quality I highly value my feet and ankles because i am a runner, that is why I spent the premium 200 for these everyday riding boots, wear about a 9.5 but ordered the 42, toes are slightly jammed but expect to feel better after broke in more. Soles are very hard which offers great protection but walking around a little awkward June 15, 2016
Very good product for the price, if these were ruined, I'd buy again. The boots are exceptional for the price. I would recommend these to anyone looking to get a good pair of full sized boots for under $300. The only thing I've had a problem with is walking around in them as the sole is very stiff, however this is going to be the same for any race style boot. Would definitely recommend these boots. Boots are slightly narrow but not so much as to make too big an impact on sizing. June 11, 2016
Good buy I bought these after a friend recommended SIDI boots. So far they have been fantastic! They were a little stiff at first, but have broken in nicely after the last 3 months. I haven't had to test their protection, but they seem to have a good amount of reinforcement in the shin, heel, ankle and toes. I feel naked riding without them. They get a little hot in the summer, but I bought these for a 3 season boot so I'm willing to put up with it. June 7, 2016
Amazing boots for the money, but a bit narrow These boots are absolutely fantastic overall, particularly given the price. I have another pair of Joe Rocket boots that weren't dramatically cheaper, and the difference is like night and day. These boots have a stiff sole and offer great ankle protection, and I like that they have a heel. I've used them in temps down in the 40s and up into the 80s and my feet have always been comfortable. That said, they are not waterproof in any way. They'll withstand light rain, but water from wet roads and heavy rains will get through pretty quickly, particularly in the reinforced shifter area on the right toes. My biggest problem with these, and it's not a problem with the boots per se, is that they're a bit narrow. I usually wear a size 9.5 in regular shoes (and 45s in most cycling shoes), but ordered a 44 based on the size chart. I'd say they fit well enough length-wise, to the point where I think a 45 would've been too big, but my right foot (which is slightly bigger than my left foot), is really squeezed in the toe area due to the narrow footbed. It's fine when I'm riding, but a bit uncomfortable when walking around. I'd say the boots may have stretched a tiny amount after almost 2k miles in them, but the right foot squeeze is only marginally improved from when I got them, so don't expect they'll loosen up over time.

Put off for years, kicking myself now (in my fancy new boots) I was riding on a pair of Vega piece-of-junk boots for 3 years. I kept looking at new, proper racing boots, but just couldn't legitimize the price. I'm really displeased I waited. For me, this was my first experience with a full boot, so yes - you do notice a change in shifting in comparison to a half boot. You can't bend your ankle as much right out the gate, but I acclimatized quickly. The biggest thing I noticed right away was the rigidity of the bottom of this boot and how incredible it felt to not have my pegs digging in to the bottom of my foot - the bottom of this spreads the pressure throughout the foot and feels GLORIOUS. It's a comfortable boot, and breathed really well. I was surprised. I'm a little nervous about how well the zipper will hold up over time, but I'm super pleased. The sale price for this absolutely sold me over the Alpinestar S-MX5 I was going to buy. Would absolutely buy again.... 2 years sooner so I could enjoy them more. May 17, 2016
Great Boot for the Money These are great boots. I've been using Sidi products for many years and these boots live up the the name. The quality looks to be excellent. I've just had them for a week so durability remains to be seen, but I see no reason why they would not be long lasting. They are not very comfortable at first. But that improves as you ride. Give them time for a proper break-in. Fit is good, I normally wear an American size 10 and size 44 fits. April 19, 2016
Strange fit... stylish, stiff.... Great looking, sturdy boot. Moderately priced. Good value. The fit, in my opinion, is actually on the large side. I bought a 44 and I am a US size 10.5. However, my heel has so much room and sits so far from the back of the boot, it almost feels as though my foot will slip out. Its not "uncomfortable" per se, but the weird thing is that it feels like my toes are pressed up quite far towards the tip of the boot. Very weird fit. I will also say that the stiffness of this boot has made upshifting VERY tricky. Sometimes I have been actually unable to get into the next gear without looking down and adjusting my foot position to get more leverage. Not ideal. Hopefully they break in some more and it gets easier. August 15, 2015
