New shoes in oven?

I saw an Instagram post/story awhile back on Emily Harrington’s feed where she put her new shoes in the oven to break them in. I’m guessing she heats them up on a super low temp and then wears them for a little while, but I honestly have no idea how this works. Anyone tried it?

I would braise my shoes before slow roasting; it would bring out more flavor. Maybe add some shallot and Chianti.
I would sell/trade my shoes on the proj way before resorting to cooking them. 

Bad idea contact adhesive will delaminate, wear them in water to give em a stretch or put a bag of water in it then freeze. 

I’ve done this many times. Works great. Recently had some boostics that were still way too tight even after a month and i stretched them a half size in a matter of minutes. Warning: you will delam your shoes if you cook them too long/hot. I’ve had a little bit of side rubber delam before, which was an easy fix with some shoe goo. 

1. Preheat oven to like 120°
2. Put shoes on a piece of cardboard
3. Put them in for no more than 5min
4. Take em out and walk around in them till they cool down. I like to wear socks while i do it.
5. Repeat if needed.

So, in Las Vegas I can just put them on my roof?

Leave them in your car, but on a pan...like those people who try to cook eggs on their dashboard.

Sprinkle with flaky sea salt, parsley, and serve warm.   

Cast Iron only, nonstick pans are a rookie move. Alternatively you can use water at or near the same temp to combine with Seb's method 

Remember to put both shoes in the oven. Otherwise you will get half baked results.

Shrimp and white wine go well with shoes. A lovely pairing. Save enough room for a chalk dessert.

I saw this on Reddit posted by yosemitebumresole:

"When we stretch shoes, we first insert a larger sized last (a mold) into the shoe so that the shoe stretches in every direction proportionally. We then run the shoe through an industrial shoe oven so that the materials have the opportunity to stretch.
Then the shoes will cool down completely and remain on the last for about a day so that the stretch "takes".

Also:
"Warning #1: If you are going to use heat to stretch your shoes, DO NOT USE A MICROWAVE. Ovens are okay, because they heat the shoe slowly and more consistently, but be careful, you don't need a lot of heat. 200F should be plenty.
Warning #2: Don't burn your foot, dingus.
Warning #3: You will absolutely void any warranty on the shoe by doing this.
Questions welcome. We stretch probably 1000 500-600 (whatever, it's a lot) pairs of shoes a year.
Edit: Amount of stretch - we can typically stretch a shoe up to a full size. Anything more than that and things get....weird. Or they break"

I have a bone spur that can be excruciatingly painful in tight rock shoes, even if the rest of the shoe is 100% comfortable. It's been a long term annoyance, always needing to make compromises.  
I finally found my dream solution: rockandresole.com/product/b… , along with a $15 heat gun from the hardware store. The stretcher "ball" has about a 0.75" diameter, which allows you to pinpoint a specific spot of the shoe upper to stretch while leaving everything else unchanged. Stretch, apply heat with gun, stretch some more, apply more heat, let it cool off and stretch overnight with the ball in place. You can permanently re-mold thick rubber rands or stretch synthetic microfiber like that. I've never had delamination issues, and heat is only applied to a small section of the shoe. The rest of the fit is completely unchanged.  

If you only have a small pressure point, I highly recommend it.
