Sidi

I bought these To replace my old Genius X . This new version with the Millennial Fit is much better. Some reviews on the Nuun dials (instead of BOA) are just wrong. You only have to use one finger to release the dial. Be wary of BTD's size chart for these shoes. Their chart states a size 47 is a US size 12. Other online competitors will show a Sidi size chart that shows a size 47 is a US size 13. The box they came in says US size 13. I made BTD aware of this, even sent some photos, but they have have not made the needed to changes to there Sidi size chart. I like the shoes. Sidi is one of the few cycling shoe companies that offers replacement parts such as the heel pad on the sole. You can spend $400 on some great shoes and the non-replaceable heel pad is worn out in a season.

I really like this shoe. I have been riding for 20 years and been in all the good brands. Recently I've been in Fizik's but the toe box is a little tight and they are all leather. These shoes have great ventilation so great in the heat of the summer. Only reason why I gave it 4 instead of 5 is when I get out of the saddle and stand in the shoes I can tell the fiber plate of the shoe is only in my forefoot and not the foot. It's fine, no big deal, but I notice every time. I would buy again. BTW I order a 44 plenty big. My Fizik boot is a 44 and the shoe is 43 (but it's too small).

I upgraded TO THE Sidi Shot3's after rocking my eRGO 3's since 2013. These are my first impressions after 100 miles in the saddle.

The Shot 3's are minimalist in their design characteristics which seems to be the norm these days. The quality of the shoe is very good. Of course, you'd expect a handmade shoe at this price point to be well built. The Shot 3 is light and stiff as advertised. The shoe offers ventilation in the undersoles and top. The shoe is constructed on a single monocoque upper with no seams which is very comfortable. The ratchet closure system keeps your foot secure. It does not have the arch strap closure which can be a plus if you have a high instep. The heel cup keeps your foot secure, and the adjustment does not require any tools.

All my cycle shoes are Sidi, 45.5 cm. When I first tried them on the Shot 3's seemed too big, loose. I compared them side by side and did not notice any meaningful length difference. I then realized that the difference that I was experiencing was the top box. The Shot3's have a wider toe box compared to my older eRGO 3's. After dialing the heel adjustment, the Shot 3's felt fine. I have not experienced loose fitting sizing issues on my rides.

The shoe does have a few negatives. First, the insole is thin and lacks arch support. The insole is comprised of Sisi's memory foam material. They should offer arch pad inserts. I'll use them for a few more rides and decide if I need more arch. Second, the heel adjustment could be better. I personally like tool adjustment solutions because you don't have to worry about loosening the heel if you handle the shoe with the heel cup to remove the shoe. I know that's probably a long shot. Second, is the weight. I don't count grams like pro cyclists, but the shoes are heavier than a few other shoes in this category. Lastly, these shoes are expensive. I'm sure the tariffs have added $$ to the price. My eRGO 3's lasted 13 years so I had to factor the useful life into the equation.

As the reviewer in July 2026 stated, the pads fit great but the screws provided with the new kit (M4x5) aren't long enough for really old (2008!) SIDI shoes, coincidentally my first ever BTD purchase, which used M4x7 screws. And as others stated I waited too long to replace the pads and had to use a Dremel 4300 to grind in a slot so I could remove the old screws and unfortunately had to reuse the ground on screws to complete the replacement. That said, still happy to rehab these old SIDI shoes rather than toss in landfill for worn pads
