best boots for bulgingly broad feet?

Another “if a shoe fits” question, sorry…

So I spent some… 6? 7? 11? hours reading about shoes.  I like the idea of a single super-gator boot.  Something not too heavy that will let me gallivant around on cascade volcanoes without losing toes.  If I go for Denali later I can buy something beefier then, or just rent a boot, or just eat more beef, or something.  I have invinci-ankles™ and can wear sandals on the approach with an 80 pound pack, so I have that part figured out…

The problem is!  Like a lot of other posts I’ve read, my foot is wide, state of Indiana wide (as another poster posted) (although that amazing width kicks in about halfway to the balls of my feet).  I can wear a size 9-wide running shoe without hurting my toes, but, due to foot width, a nice shoe-lady at REI just sized me into a size 11 Scarpa Charmoz.  The size 10 started to hurt a minute after I put it on, in thin running socks, while sitting on the shoe-fit bench at the store.  The size 11 just feels weird, and despite stuffing a Superfeet Orange, and some other boot-filler-thing underneath it that she cut for me, I still have some noticeable heel lift.

So I guess, I’m going to sum up what I think I have for all my options, ask if I got it right, if I missed anything, and what people think of my calculatory prowess, and ask if anything is possibly custom-fit-able?

From narrowest to widest, of the currently in-production models of super-gators:
Arc’teryx Acrux AR -> La Sportiva G5 -> Lowa Alpine Ice GTX -> Scarpa Phantom Tech -> Boreal Stetind

Summary of options' sizes:
Arc’teryx is “too narrow to get my foot anywhere close to the sole of the boot without going size 23.5”
La Sportiva is great “if your foot fits” and it isn’t “as narrow as it used to be”
Lowa is “averagish” (pretty green color tho)
Scarpa is “the go-to wide-foot option with great toe-box room” except for “the Tech is a lot narrower in the toe-box than every other Scarpa model”.
Boreal is “a giant box that your heel will flop around in” and “toes may or may not be roomier than a Scarpa?”

There’s also the discontinued boots-that-I-can’t-find-outside-of-Ebay options:
Scarpa Phantom Guide is “roomier in the toes than the Tech, and discontinued…”
Salewa Pro Gaiter had “a neat adjustable sole-flexy feature, a wide-fit option, but is also discontinued…”
Mammut Nordwand High GTX is “a wider boot, but maybe not as wide as the Scarpa? (and discontinued)”

I really like the Tech: it’s flashy, great colors, I think the fluffy sole idea for the extra light weight & extra insulation is pure genius, and wow those colors are bright; but I’m scared of the fit.  Ski boots appear to get customized all the time.  Can customizers customize synthetic mountaineering boots, or are the materials too different?

I was also looking at the Mammut Nordwand 2.1.  I know it’s a double-boot and a pound heavier than the Tech, but it flashes just about as well as the Tech, it’s cheaper than the Tech, and it has a mammoth on the back.  The ski-boot customizers appear to have a relatively easier job customizing the inner boots of their ski-boots.  Since the Nordwand 2.1 has an inner boot, will that somehow enable me to have it customized for a perfect fairy-tale fit (despite it being enclosed in an outer boot…)?

summary: should I
go Scarpa Tech due to the Giganotosaurisian gonads of that manly engineer who declared, “you know, that part of the boot that you walk on, let's make it so you can't walk on it”, and someone tell me it'll fit?

go Mammut Nordwand 2.1 because there's a chance I can alter the inner boot to make it fit reasonably ok and there's a mammoth on the heel?

go Boreal Stetind because it might actually have the room to let me wear it in a size 9, and even though my ankle will still slide around with cedar shims on both sides, it doesn't matter cause I have invinci-ankles™?

go Salewa Pro Gaiter “insulated fit” (+4mm!) because you meant to buy the “performance fit”, procrastinated through your return window, and then forgot you left them in your closet for 3 years?

option E?

option Ω?

Thoughts?  Thanks!

I share in your plight, my arches are collapsed and my midfoot is so wide that in some ski boots my foot floats instead of making it all the way to the foot bed!  I've found that I can get by in Scarpa Charmozs but they suck until they break in and soften up.  I actually fit in the La Sportiva Nepal Evo Cube better than the Scarpas.  If I were looking for boots with built in gaiters I'd probably start with La Sportiva since I think all of their winter/expedition weight boots are built on the wider last similar to the Nepals but I could be wrong.

I've made ski boots work by going for Atomic Backlands with "memory fit" and stretching the entire shell in an oven and then having a boot fitter punch them even further.  They are actually remolding the plastic shell, not sure they can do that with leather and textile boots.

If you do need something warmer when you head to bigger mountains you should look into overboots/insulated gators once you find a boot that fits. 

I have not tried them personally but have heard that Salewa makes wide boots. Sorry, that's all I can contribute, my feet are narrow. Best of luck!

From Raf's reporting at The Alpine Start, next year's Phantom Tech appears to be wider in the toe box.  Not sure if "wider" will accommodate your needs, but it may be something you want to wait to try on before investing in a pair of boots right now.  The new model also has additional Aerogel insulation, they're 100 grams lighter with a stronger outsole and possibly $50 cheaper than the current model. 

I have 8.5EEEE feet, low collapsing arch, high volume.

I ended up going to mountain shop in Portland for a boot fitting after multiple years of struggle.

I don’t remember his name, but the man who helped me is a boot fitting sage. (At the time he just came back from a Nepal climbing trip with his 12 yr old daughter. Total badass)
We ended up with Nepal Evo 42.5 with custom boot stretching + green super feet.
Totally worth the money & work. I’ve had these boots for years and for the first time not had terrible pain.

"11.5" on a brannock device, but the smallest street shoe I fit into is a 13 (for non-wide variants). I have a low volume foot (low arch, very flat wide). Like others, my foot widens well before the ball (the outer metatarsal splays outward in a weird way). Years ago, I ended up in the phantom guide (the original orange one that came after the yellow one, but before the new orange/blue ones). They were the only ones I even came close to fitting into (size 47 for reference). This was back in 2011 though and boots have changed a lot since then.

I continue to have a host of foot problems from hiking, biking, climbing, and running, but I've recently found a lot of help from Spenco Rx Orthotic Arch insoles. I find that getting that arch support not only helps take a little weight off the balls of my feet (reducing foot pain), it also increases arch height and foot volume, which tends to help shoes fit better. Another benefit of the arch support is that it feels like it narrows my foot a little where it is wide before it should be.
