sidi sizing vs giro or shimano
Moderator: robbosmans
It's been a while since my last sidi shoes, anyone know how the sizing runs vs shimano or giro. I'm a 45 in both shimano xc90 mtb and giro empire road shoes and was going to order sidi wires in 45, but some people say order half size bigger and some say there about the same? For reference both shimano and giro 45 are spot on for me in length and width.

Shimanos are pretty bog standard in terms of sizing.
Giro Empires are narrow in the forefoot, but the uppers are flexible enough conform around wider feet.
Sidis are narrow in the forefoot with an aggressive taper in the toebox AND they have low height/volume. That's why some people go a half-size larger. In reality, it would probably be best to just go with a shoe that fits better...

I have Empire slx and Wires, both in 47. There are no halfs in these sizes. But even if I had a choice to go 47.5 with Wires I wouldn't.
Sidi Wire 45 and Shimano 45's before. I don't think you need to size up for Sidi.
Thank you, I'll end up going the same as the others then. I would actually prefer a lower volume shoe since the shimano shoes I had to cut the straps because when I pulled them tight the straps were way long and the empires the laces have to go around my foot before tightening or too long also.

I have no Sidi, but 46 for Shimano and 46½ for Giro.
Shimano 46½- way larger than Giro (i use standard, NOT wide Shimano).

I'm 43.5 in Sidi and 43 in Shimano. Never worn Giro.
I just bought SIDI Wire 2 Air’s. lovely shoe. They must have changed sizing as I am in a 44 in these and in Shimano 321’s (my old shoe) I had 44.5. The SIDI has more room across my forefoot which is great as I get a bit of pressure against the outside of my little toe in the shimano’s. I have only done 1 ride on the SIDI’s but really like them.
