Shoe size - Sidi Ergo 2 Carbon

bridgfordkid

My first road shoes were Shimano R086s. In a 45. Thought they fitted ok but I'm getting numb toes and side of feet where they are pressing up against the shoe. Whilst I'm fairly new to road biking I've managed to get a place on the RAB 2011 and thought 'sod it' I'm gonna get myself some top-draw shoes that'll last years and be really comfortable. Ordered some Sidis online in a 46 as I've seen a few comments to 'size up' on various boards. I'm just a bit worried cos they were 185 notes and I don't want to get it wrong again. There is space at the front but I'm assuming that the 3 fasteners and the rear heel cup will keep my foot in place such that space at the very front won't matter but will prevent me getting the numbness. I don't have narrow feet but they are mega wide. Any advice? Cheers.

try before you buy. i would have thought the sidi genius 6.6 would be better fitting. maybe go over to chain reaction cycles if there isnt a lbs that has a wide range of sidi shoes

Shimano are pretty well known for narrow fitting, although not used their shoes in a while. I find Sidi's about average, not especially narrow but fairly snug. I went up a size over trainers but have done that on Specialized shoes to. Not sure where you've ordered from but you should be able to send back if they're unused (i.e. don't fit cleats before trying them on...). Having said that my Spesh s-works shoes feel a bit tight when off the bike but work great on-bike, if I'd have tried them on in the shop first I probably wouldn't have bought them.

Bike shoes need to be snug - you want to stop your foot moving around in them and should certainly not have the same room in them as a pair of trainers - but if they are too tight, they will restrict blood flow and your feet will hurt. With Sidis I generally take one Euro-size bigger than other bike shoes. There isn't much breaking in with bike shoes either, the use of synthetic, stretch resistant material means either they fit or don't - if they feel tight, they'll stay that way, particularly as your feet tend to swell during a long ride.

I think you should try the same shoe in a 45 MEGA size, this may give you the extra space in the toe box, without being too long for your foot.

I found Sidis come up really small. I take a 42-43 shoe size and wear 44.5 in Sidis. I too suffered from numbness in my toes and got rid of it by moving the cleats back as far as they will go.

One cure for numbness IME is simply to wear your shoes a little looser. When I first got my Sidis I was cranking the ratchet down hard and my feet were going really numb after 15-20 miles. Now I run them a bit looser and they're fine.

FWIW I take a 43 (9) in street shoes and a 44 in Sidi road shoes.

My Shimanos and SIDIs are the same size (47), the SIDIs are a bit more snug in the width and I have to micro adjust the rachet occasionally if my toes get numb.

Other than that great shoes
