Keep hearing different things about the sizing. some say size up/stay same.
SiDi MTB Drako Carbon SRS are the shoes in question.

their guide isn't all that helpful, I use 42 in both specialised and shimano. I have 26cm length feet. +/- a few mm.
would you recommend I stick with a 42? just don't want to order a 42 and they are to small.
The option to try them on isn't an option with no dealers locally.

I have a chart I found somewhere that lists many different shoes manufacturers and how the sizes match up. Doesn't have specialized tho, but Shimano and Sidi match up at size 42.
But my size Sidi 44 matches up with shimano 44.5.
US Shoe size 10.
Not the best but might help you out a bit.

Short story I would stick with 42.

We sell both Shimano and Sidi. In more recent years Sidi has had more standard volume to there shoes. Still a little bit less volume compared to Shimano but volume/size difference more akin to comparing a Carbon sole race to a standard cycling shoe in the same brand. Think performance fit not drastic difference. Where say 3 years ago they did run much less overall shoe volume. The Sidi rep (a bias source) said that Specialized tried to replicate Sidi fit. As the story goes they would ride with one shoe Sidi and one Spec to try to have them match when they were developing there shoes. Maybe just a good story but that at least says the fit should be very similar.

I generally take 42s but ended up with 43s (Sidi Eagle 6 carbon) but I think you should start with the 42.

If you can't get to a shop my best advice is mail order from somewhere that will take them back. I bought 2 pairs and sent one pair back.

Someone is bound to say Sidi are narrow so why did I find them short/wide? I explain it thus: I have narrow feet so normally wear shoes a half size smaller to get a narrow fitting and my toes have to be near to the cap to achieve this. Standing between 2 boxes I measured my foot length at 26.5cm. The 43 Sidi foot bed is also 26.5.

I believe Sidi is sizing is as good as it can be given people's feet are not all the same shape; you should start with the 42.

Over time the shoes have eased up width-wise and I now run double foot beds to make them narrower but I still don't think I want them shorter.

I wear 45 shimano and 45.5 sidi, 45 sidi seem just a hair short.

I need MTB shoes for my MTB. I'm going to go with Sidi because I've had a pair of Sidi road shoes for about 15 years and they are still holding together (my first pair of road shoes from Shimano lasted about six years with the sole continually delaminating).

My Sidi road shoe is size 47. Can someone advise me
a) Have the lasts changed significantly in the last decade or so? (I know they have standard and 'Mega' fit...my feet are quite narrow so I'm happy with the standard fit).
b) What are the differences between the various models in terms of fit? From what I can gather:
Drako - Full wire closure. Adjustable heel retention. SRS Carbon-Ground Sole (with replaceable lugs)
Dragon - Buckle plus single wire + velcro. Adjustable heel retention. SRS Carbon Composite Sole (with replaceable lugs)
Cape - Buckle plus double wire. Competition sole.
Spider - Buckle plus velcro. SRS Carbon Composite Sole (with replaceable lugs)
Eagle 5 Fit - Buckle plus velcro. Competition sole.
Dominator 5 Fit - Buck plus velcro. Competition sole.
Buvel - same as a above but with simpler straps

All the differences seem to be defined in terms of buckles/closures and soles. Do they all have the same fit?
Based on that it would seem that if you wanted to keep the shoes for a while you'd have to choose one with an SRS sole as the Competition sole doesn't seem to be replaceable.

I'm using Sidi Drako and Wire, both in 42 size.
Take one size up (ex. my normal shoe size is 41).

I find most SIDIs just about true to the "typical" size. There are some exceptions. Latest Cape run ~ 1/2 size smaller than Drako etc. Most SIDIs run on the narrower side IMHO. I am probably 42.75 and slightly wider than normal (not wide enough for MEGA). Drako 43 is slightly tight for me but this could be due to fairly stiff upper and some uneven pressure. Drako 43.5 feels much better but has no perfect snug. Dragon 3, Dominator, Eagle 5 Fit, are same sizing as DRAKO from my experience but wire lacing in DRAKOs allows for much snuggier fit. Mavic Fury 42 2/3 is a perfect fit for me but the upper is a bit too soft IMHO. Gaerne Kobra 43 is just about perfect - perfect snug and a little extra room in front of the toes. Latest Gaerne Sincro has slightly different sizing and 43 is too long too wide for me :-(; fortunately 42 fits me perfectly.
Northwave. Extreme tech MTB Plus is a 43 for me (they seem to run slightly wider than SIDIs). Northwave Extreme Winter GTX - my best fit is in 42.5 (43 would be great if thicker socks were to be used)
So sizing and fit varies between manufacturer and between models. It's best to try before you buy.

I've been running Sidi for the last 10 years. Genius, Ergo, Logo and Wire for road. Eagle and Spider for MTB.

I've run 44 throughout and all fit well. I've found vernice uppers to be less supple than Lorica and have taken a bit longer to get comfortable but also easier to keep clean. Latter model Wire and Spider have had a more generous toe-box but critical fit around the mid-foot and heel remains the same, so no movement/slippage.

As for fastening systems (which are mirrored across road and MTB ranges), I've found the buckle and dial combo on the Ergos the best. Velcro on the Genius and Eagles eventually gave out but I managed to extend their life by gluing new loop strips to the mid-foot straps. Wire gives a very even tension but the mechanism is a bit fiddly to operate with full-finger gloves on.

I went for the Spider for the replaceable sole system but notice that the material wears quicker than that used on the non-replaceable Eagle so I'm not sure of any long term economic benefit. Then I found this post about a guy who did a clever DIY replacement on some Dominators:

https://tandemgeek.wordpress.com/2010/0 ... nkenshoes/

I've never tightened the heel retention system on the Ergo and Wire. Mostly because I've haven't felt the need to (no heel lift) but also because friends that did experienced rapid wear to the fabric lining in the heel cup.

The good thing about Sidis are that the uppers are consistent fit and quality so its really a choice around fastening system and sole.
