Sidi boot sizing

[hogo]

I was thinking about buying a pair of Sidi On Roads. I've worn shoes that range anywhere from 10.5 - 12 US. My feet are 28.5 cm. Anyone have any suggestions for sizing?

I just got some Sidi Adventures. I needed a size 47 which is the first time I've ever worn a size 47 (12.5, I usually wear and 11 - 11.5). I've found Sidis to be a bit narrow in the toe box but I also needed the length. The 46 was just too small.

but i found the sidi adventure boots (goretex) to bee sized rather on the big side of things.... I bought mine a size smaller than I normally would have, which I found odd. My other sidi boots and bike shoes are all 42's. The adv boots needed a 41. They have a lot of volume.

I should add that I tried mine on using Superfeet insoles (I recommend them over the OEM insoles but they do take up some space). I also used lightweight and medium weight socks. The perfect fit was with the insoles and medium weight socks (I wanted to leave a bit of space for cold weather riding).

I'll suggest that the bottom-line is that one tries on different sizes before buying just about any shoe, let alone a $380 boot.

Three-cheers to the Lynnwood Cycle Barn (Seattle) for stocking Sidis, Alpinestar Scouts and the similar Triumph boot. I also tried the BMW Santiago but couldn't find a great fit.

Good luck!

I wear 10.5-11 and my Sidi Crossfire and Adventure in 45 fit perfect.

I live about 15 minutes from Lynwood Cycle Barn, I wonder if they have the On Roads in stock?

Looking at this size chart it looks like I would be around a size 45 maybe a 46. Japanese sizes are in cm fyi.

My feet are about same size as yours (~285mm). I normally wear 10.5-11 US size, 43-44 european but w/ sidi I had to get 46, both crossfires and vortices.

I suggest trying them on before buying, I've heard some say sidi's are true to size, I guess that has to do with witdh and heigth of your feet.

Just bought a pair of clever airs and a gore Tex sidi boot. Both fit true to size I have to say, they are super comfy and so far I'm very pleased with the purchase.

Fella's,

I've been looking thru tons of posts in various forums and have decided the Sidi Crossfire AT or Charger is my next boot. I wanted something more substantial and with much more protection than my current TCX Infinity GTX. They are too soft and no support standing on the pegs. I think my Scarpa hikers have better protection.

My foot is about a 9E US. In most EU sizing, I run between 42/43 depending on make. (Scarpa, Asolo, etc) I tried on the 42's too snug, and the 43's just a bit loose in the heel with a little room in the toe box. The width of the 43 felt pretty good in the brand new boot at the store.

I always wear a polypro liner sock and a medium weight merino wool blend outer sock. I do ride in colder weather (15*-20* F) so I wanted a size I can always add a thicker sock also.

My question is,, have others had the Sidi boots stretch in width after break-in? I can't see them stretching much if any due to the amount of synthetic material the boot is made of. I just don't want to drop $400-$500 bucks on a boot that don't fit.

Thanks for any insight on the matter.

Hello,
Something doesn't add-up about Japanese size being in centimeters. There are 10 mm in a cm so you can use the top row for cm.
Cheers, Steve

I am a 10.5 US and wear a 44 in both the Canyon and Discovery. They fit very well for me and I have a medium volume feet.

I have Sidi On-Road and I believe that they run true to size. They ARE a bit narrow. I compared them to other European-sized boots and shoes since American sizes are all over the map (today I wore sizes 8.5 and 10.5 and both fit fine).

[SteveROntario]

Wow, I just measured my feet while looking at the Fleamarket. The SIDI mm table is totally wrong, I measured 250 mm and they call that a 5 US!! I wear a 9.5 US.

I've had a pair of On Roads for about 3 years. I bought them on-line from Revzilla so all I could do was trust the sizing guide when I ordered. I wear a size 11 US and have a standard width foot. The tag in the boots I received showed the following 4 sizes:

EUR 45
UK 10.5
US 11
JAP 28

The boots fit me perfectly just like any other shoe or boot I would normally buy here for the US market in a size 11. All I can say is Sidi seems to have nailed the US size correctly.
