Has anyone grafted SPD cleats onto winter boots?
I know this may be more appropriate for the winter forum, but the only reason I want foot retention is because I'll be riding FG this winter. Otherwise I wouldn't care.
I don't want to use clips and straps because I can't cram my bulky boots into them. Plus, they're a pain with mittens on.
I don't want to use my SPD shoes, cause they're really not appropriate for snow. So the obvious answer seems to be winter boots with SPDs. Anyone done this? Even if there are boots already available for clipless use, I would bet that they're far out of my price range. I won't be spending much money on this if I do it. Thanks!

As stupid as modding SPDs on to sneakers is, I think it makes sense with winter boots. You will have to get some pretty small profile SPD pedals (like these) and a big profile boot, with lots of room. Unlike with the sneakers I think youre also going to have to carve out where the spindle will be going through, as well as enough room to twist our of the pedals.

I've used Pearl Izumi shoe covers for commuting use and they performed fine. Admirably, even. I suppose it depends on how much you plan to use them -- they won't last forever, and they're admittedly a bit of a pain to put on. If I lived somewhere that involved daily riding through the snow, they wouldn't cut it; but in that case, I'd sooner invest in a cycling boot or just ride without retention than hack up a boot for what I can only imagine would be meh results.
To the OP, how much will you ride in the snow? Are you sure it's enough to bother with clipless boots?

I'm mainly concerned with how I'm actually going to screw the cleats in. I'm assuming the rubber sole won't be adequate. I was trying to look at my SPD shoes and it seems like there's a metal plate about halfway inside the sole. I need to figure out how to get one of these inside the sole of the boot.
Kayce, why will I need low profile pedals? Wouldn't anything work?

Shoe covers don't last, are a pain in the ass, and don't really work anyway.
Just get these and be done with it.....
They will keep you cycling all rear round for several years, making them a worthwhile investment. A big thick pair of socks with a pair of these and you are ready to go. Any boot that you mod up isn't going to work as nicely as the real thing and you are going to spend more time ****ing around with it than its worth, and its probably not going to hold up well anyway.

How to do it. I also have heard about using a shimano spd adaptor to make homemade spd.

The reason I suggested a small profile pedal is that with boots you will need to cut away a large section of your shoe, much more than with sneakers.

This is a winter cycling issue. Please post it there: https://www.bikeforums.net/forumdispl...Winter-Cycling. They won't care if you have 1 gear or 20.

You should try powergrips. The x-long ones were more than enough for my size 14 winter boots. Also, they are zero hassle, with no moving parts and nothing to freeze. https://powergrips.mrpbike.com/index.php?section=index

I'm using extra sized Shimano SPD sandals. Up to four socks tested in conjunction so far, very comfy at 15F. Thin sock, Sealskinz, Big cotton sock, all inside the sandal, then a bootie outside of the sandal. Lots of room for toe circulation.

Applying SPD cleats in the usual manner by drilling the sole and using a metal back-plate will compromise your winter boots and put a heat-sink inside.
Boot soles are usually too wide to position the cleat correctly in the centre of the sole, unless you use a pedal with an extra long axle.
I would reconsider toe clips, metal ones with leather straps. Why do you need to use your hands with toe clips, there is no need to tighten the straps, they work pretty well lose and are quicker and safer than tightened straps. Tight straps were only ever used by race/high performance riders.

funny, i suggested this once on this forum, modding sneakers to use with SPD cleats, and i was immediately shot down by all the forum users. people were PISSED at the audacity of such a thing. I never ended up doing it, but i still want to try it with a pair of football cleats from a thrift store.

While I absolutely love mine, I completely understand that not everyone can afford a set of Lakes. A homebrew pair using old hiking boots, Toasty Feet and some silicone sealant may be a perfectly valid alternative.
I'd like to hear how it works out for the OP.

I'm not sure where you are, but the OP is in Wisconsin. I worked in Wisconsin one winter. When it got UP to 15°F, it was sufficient cause for celebration that we broke out the palm trees and hula skirts.

I'm in MN. 15F today, and yep, plenty toasty =)
It is a bit inconvenient, yes. I leave the bootie on the sandal when I'm not using, it stays put for easier application later.

I'm in east-central WI (Manitowoc) and just don't bother with clipless or clips. My commute route is usually plowed okay but there are plenty of days where due to the unpredictable timing of storms, plowing, and other variables it just wouldn't be wise to attach the feet to the pedals. I use studded tires (Nokian Hakkapeliitta W106) and still have to quickly get off the pedals once in a while. The studs are a life-saver. But when the brown sugar is deep enough, even studs aren't always enough to keep the wheels from quickly kicking out from under me.
I switched to BMX pedals to accommodate my hikers.

You will need a pair of light as possible winter boots two or three sizes over your normal foot size. First you need to find some 1/4 in thick engineering plastic. Nylon works well as will ultra high molecular weight polyethylene. Other plastics will work but it need to be a plastic that is very stiff but slightly flexible and is not super rigid and hard. Acrylics and polycarb will not work well. An even better approach is to make your own custom foot bed from fiberglass and epoxy resin. You will need a little of this anyway for another part.
Take a router or knife and cut out the lugs on a small portion of the sole under the ball of the foot. Only remove enough to make a flat area large enough for mounting and SPD clip. If the remaining lugs on the sole are deep enough you will be able to walk around normally with the SPD clips installed. You need to make a small plate out of fiberglass and epoxy resin so that the SPD clip has a hard surface to be tighened against. You can also use aluminum here but it will make the shoes colder and not as warm. THe original outer sole material is too soft for the SPD clip and binding interface and will not transfer force properly. So you need this small hard surface under the SPD clip. Then you put your stiffening midsoles inside the boot and drill holes all the way through the sole and through the custom midsole. You will need to then counter sink the holes in the midsole and use a flat head cone shaped bolt so that you have as little bolt head sticking above the midsole surface as possible. T nuts also work well and better in some cases.
Then you just put a little silicone glue on the outer SPD plate and tighten the hole thing together. You may have to put a small amount of padding over the midsole to cushion the bolt heads. Generally the thick felt boot liner is sufficient if you have the bolts countersunk enough.
This method works best if you start out with a lightweight boot to begin with. And the more layers of foam that the sole of the shoe has the warmer it will be. The right sole is the most important part of having a warm shoe since the rest of the foot can be easily insulated with wool socks if the boots are not too tight fitting.

What kind of outer boot do you use over the sandals? I picked up a pair of oversized LAKE SPD sandals last summer to try something like you are describing. I was planning on wearing a felt pack boot liner with a homemade gore-tex overboot and then strapping the whole thing into the sandal. How does your setup work if you step into some 1 or 2 inch deep water?
