Sidi Genius 5 Mega shoes: width issue

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them.

Sidi Genius 5 Mega shoes: width issue

The size 45 Sidi Genius 5 Mega shoes I picked up off Craigslist a few weeks ago are terrific, but they're just a tiny bit tight on the sides. Forty-five minutes on the trainer is enough to leave the right side of the arch on my right foot quite sore.

It's the edge of the sole that does it; it curls up just a smidgeon under the edge of my foot. Has anyone ever heard of a way to flatten edge of the plastic sole?

Or, would the 45.5 shoes be a bit wider?

I've previously worn Sidi in both their Mega and Standard widths. In both cases, the shoes were noticeably wider the second season that I had them; they stretched out a bit in both cases. On the standard width shoes, I successfully used wooden shoe trees to expedite the stretching process. I've also read that steaming them up in the shower followed by the tree shoes will work, but I didn't try that.

One more thing, consider trying different socks. Thinner socks might buy you a bit more room in the shoe, but a thicker sock might give you a bit more padding. Who knows?!

I hope it works out for you. Good luck.

Thing is, it's not the leather that's the problem, it's the lip on the edge of the sole. I wonder if there's a way to flatten it out?

Maybe better insole than the sidi one, maybe the scott one if you can find one, or maybe the specialized bg. Sidi insoles are not that awesome.

From what I recall on the Sidi website, the bigger sizes are indeed a bit wider. I fit into a 45.5 Mega really well but went up to a 46 on a recent purchase to get that extra bit of width. Check their website for info on the width increase - that might let you know if the increase is enough for you.

^^^^^That, plus you can just take them to a shoemaker and have him stretch them out for you.

Suerfeet Yellow seemed to be preferred by Sidi users.

There's also Louis Garneau and I think Specialized as well.







NOTE: When I got my Sidi Raidens, they were a little snug also,
but after a couple hundred miles, they've conformed to my feet.
They do (even if used) need time to be broken in to each rider.

The type of Surefeet insoles depends on the amount of arch support you need so try them before purchasing. I have use the blue Surefeet and love them.

I have 45 Mega's due to foot pain/swelling issues after extended periods of riding (left forefoot, sometimes the right). The insoles were total ****, in the end I just removed them and now ride without insoles. Maybe I am just fortunate in that I don't need the support in the arch area that many do.

Second (third? fourth?) the insole reco.

I'm using Superfeet in my Sidis, and they're a huge improvement on the Sidi insoles.

Well, I got back from the local shoe repair guy after a second round of stretching. He said I should try them without insoles, so I did...and they fit much better and are very comfortable, at least according to one 45-minute ride on the trainer.

Any reason I shouldn't ride sans insoles? Said shoe repair guy did say he had some nice, thin leather insoles that would be a good option if I really wanted insoles. I'm willing to try them without, first, but is that a bad idea for any reason?

What's the inside of the Sidi's like under the insoles? If you don't need the arch support from insoles, the only thing I can think of is if there are rough spots such as from stitching inside the shoes. If so, you could start wearing holes in your socks - which leads directly to bloody holes in your feet.

Doesn't seem that rough, but even so, I think I might investigate the ultra-thin sole option.

I have been riding with my insoles removed for several years with no issues. Have not found anything inside that would wear through socks, and I wear ultra thin socks. Do some more trainer time, then look at your socks afterwords. I am sure you will find out that there isn't anything inside that will wear through.

I have exactly the same problem. My Sidis are the most comfortable shoes I've found so far, except for this one part. I don't get why they think that the bottoms of my feet are rounded like that. They're plenty wide though--the upper fits my foot well. The problem is the pressure on the outside where the sole joins the upper.

The solution for me has been two things, which I found after quite a bit of experimenting. The first was to use a rigid 3/4 length orthotic insert, which dissipates some of the pressure into the midfoot. That way, I don't have all that pressure concentrated under the forefoot. Second, I took a razor blade and shaved away the cardboard-like midsole material inside the shoe. You need a really sharp blade (I went through 2 or 3) and a lot of patience, and you have to be really careful not to slice through the lorica. I bent the edges up a bit to make it easier to shave them off. It made a huge difference for me.

Another option is to use some Sugru or Instamorph (the first is room-temp curing silicone putty, second is low-temp moldable thermoplastic) to sort of fill in the dip in the middle and form the sole so that it matches the shape of your foot. It might work to smear a bunch of Sugru in there, put a piece of parchment paper or something over it, and ride on the trainer to mold it in, taking it off periodically to shift the putty around to the right spots. Get it where you want and let it cure. Then lay an insole over it and you should be good to go. The downside of this is that if you screw it up, it's going to be difficult to get that stuff out. You could stick a piece of parchment paper down on the bottom of the shoe and mold the putty or plastic over that, then remove the paper and glue the molded piece in once you're sure it's the right shape.

Below are a couple of pics of my setup I describe above. I cut the little line of stitching that holds the tongue in place, because I needed the space to get my hand and the razor inside the shoe. But I haven't noticed the tongue moving out of place on me. If it does though, you could always sew it back through the same holes you cut--it's only about a 1/2 inch line of stitching.

Thanks very much for the ideas! I'll try the 3/4-length insert first and see how that feels.

Update: With the warmer spring weather, I've been riding outside for the last while without the insert, and haven't had any issues. The shoes feel good. I suppose I'll have to wait until it gets hot and my feet expand from the heat to see if any further action is needed.

I'm guessing it's a bit warmer in my basement than outside, which might be a possible explanation for the trouble inside but no trouble outside.

One more update (the last, I promise):

All this time I've been riding bow-legged. Jeebus. It suddenly occurred to me the other day that my knees were fairly far away from the top tube. So I squished my knees closer to the top tube, and guess what? No pain in the shoes.

All this time I've been pressing on the pedals at a slight angle, and that's what caused the pressure and pain on the outside of my right foot. So I've solved the problem. The shoes feel great, now.

Whuhoo!

Yep, same with me. Try some IT band stretches (or myofascial release with a foam roller)--those knees will some in naturally if they're not already.
