Has anyone done this ? I've herd that people put foil in the bottom of there shoes to stop cold air from coming up ?
Does it work?
Any info cheers guys

I have done it in my shoes I wear in winter and can say it works a treat! Cheap and before I go on a ride I stick them on the radiator and they seem to hold heat for a bit longer than without it. Nothing lost giving it a try.0
-
I have used some foil under my helmet for extremely cold days - that seemed to work.
Be a devil though - risk a piece of tinfoil yourself and see what you think ? What's the worst that could happen ?0 -

Are there degrees of protection? Would one get a better result from that stuff you use on Turkeys? Or will value foil do?My blog: http://www.roubaixcycling.cc (kit reviews and other musings)

Got some insoles that I use in my winter boots. Fleece upside, foil on the bottom.
Not sure how much it adds but what's to lose0 -
Used foil a few weeks before Christmas when it was around 2degrees C and I had lost my overshoes. Wrapped toes and base of foot in some cheapo foil and it definitely kept me warm. I was worried it might be uncomfortable but I hardly noticed it at all. The only downside was that foil was thin and broke up and I was picking bits of foil out of my shoes for days after.
Sometimes. Maybe. Possibly.

Rather than wait ages for foil to warm up on a radiator, how about a quick 30 second blast in the microwave just before you head out?0

Tin foil under a cycling helmet helps with the voices too.0 -
Essentially it would be an emergency blanket for your feet.
No reason at all why it wouldn't work.Postby team47b » Sun Jun 28, 2015 11:53 am

Aluminium "tin" foil has no heat retaining properties. The only way it keeps heat in when its used for cooking it to reflect the heat back. It doesnt actually store any heat in itself. If you want to line your shoes with it, you are probably better using something thicker and waterproof like a peice of plastic cut to the same shape is your insole. I piece of foil less than a mm thick is going to do SFA to insulate your feet.0
-
Well it is waterproof and will stop the draft from the holes and as you say - will reflect the heat back.
If it's used in survival blankets its not going to be completely rubbish.
(mind you I've used a bin bag as an extra layer in the alps so plastic has its uses too !)0 -

Sans foil and anything else metal hopefully.0 -

If you wouldn't be seen dead wearing aluminium:

Not necessarily

I believe thickness is irrelevant. The metal will reflect heat back inside the shoe, rather than act as a traditional insulator. Foil based blanckets have been used for ages in emergency, they work very wellleft the forum March 20230 -
This "foil reflecting heat" is a lot of cobblers in my opinion. Aluminium is what they use for heatsinks so it's just as likely to conduct heat away from your feet.
The reflective survival blankets are plastic so maybe more likely to do a better job in this respect than Bacofoil.0 -
If I can be arsed to remember I'm gonna sacrifice a bit of my freebie foil blanket in a show down v tin foil for my weekend ride. I bet I won't notice the difference. Ideally I need a third foot to go without any protection but this isn't practical sadly.0

Tried it today with my overshoes and seems to stop the draft from underneath and water coming up through the vents .... Would say its amazing but it works so that's all that mattersWhen i die I just hope the wife doesn't sell my stuff for what I told her I paid for it other wise someone will be getting a mega deal!!!

You forget that you've got a sock insulating the foot, so the foil isn't making direct contact with the skin. With regards to reflecting heat; that's exactly what the foil does - it reflects the infrared part of the spectrum. Why do you think you can buy space blanket loft insulation, or why you can increase the effectiveness of a camp fire by putting a space blanket behind it, or decrease your heating bills by putting a foam-backed space blanket behind your radiators?0 -

And what is a space blanket made of? Quite frankly you're making my point for me.0 -
Anything with a reflective surface will reflect heat. That could be alu, plastic, glass or many other materials. It all depends on the shininess on how much is reflected. Tin foil will reflect some heat but the sheer thinness will mean that in a shoe the exposure will negate the heat its meant to reflect back. A more insulating material will prevent heat loss from your foot than a piece of thin metal sheeting which will actually help draw heat away from your foot. Tin foil eventually breaks up and loses the shiny property you hope will keep you warm and you are left with a thin piece of metal stuck in the bottom of your shoe. Why not just use a thicker more insulating material than metal which relies on other properties than reflection which in this case is none at all.
In the winter months I have decent high ankle socks, normal shoes. On top of them I have a pair of sealskins shoe covers and in extreme cold or wet a pair of Castelli Booties. None of them were bank breaking in cost and they keep me warm. Layer system works a treat.0 -
I think you're overthinking this.
He's got shoes with holes in the sole - the tin foil blocks the holes
- so no drafts - tick
- its stopping the water coming in too - tick.
The foil WILL help keep the heat in - check this basic thermal camera vid - https://www.youtube.com/watch?v=yOXWufRbe2Q
As to the foil breaking down - its kitchen foil - its almost free to make another insole. One roll would probably last a lifetime.0 -
Some of my riding group wrap clingfilm over their socks. Supposed to help ieep your feet warm. Dunno!0
-
I tape over my vents on the sole with electrical tape in winter. That and toe/shoe covers are all I've ever felt I've needed.
Then again if it goes too far below zero I find the turbo has an instant appeal so maybe I'm not testing this properly 0 -

in this context the insulating effect is due to reflection of thermal ir and blocking vent holes, it's the same whether shiny al foil or metalised mylar filmmy bike - faster than god's and twice as shiny0 -
I wrap my socks in cling film before putting my winter boots on, imo works far better than foil0

In the olden days it was bread bags on the feet. You young folk with your modern cling film n'all....0
