Agree. My experience with Santoprene TPR material is fairly dated. Although the processing point or glass transition temperature of that material is 320-350F, I could see how even moderate temperatures could make shoes feel softer. Especially with the weight and power of a professional footbal player on top of them. But originally I was reacting to the sensationalist headline stating the shoes were melting. Today Ai headlines can basically state anything to get clicks and rarely get called out. We are just desensitized to that garbage. I’ll get off my old man chair now.
Vulcanized rubber usually refers to natural rubber from plant material. Tires are thermoset, EPDM ( ethylene propylene diene monomer). EPDM is vulcanized or cross linked with either a sulpher or peroxide based system. As are shoe soles.
Edit: the long chain polymers are cross linked not cured which changes the plastic or elastomer to a thermoset which will not melt
Most TPRs (thermoplastic rubber) materials melt above 350F. Most shoes are made from thermoset materials, ie the same material as tires which once cured do not melt. Although the field was likely much too hot for athletes to be comfortable or even safe, the title is complete bullshit.
Look There’s Dad. Great video.

Tobacco hawk, moth. Found adjacent to my tomato plants, this moth will likely spawn tomato hornworms which will be devastating. But it’s part of the ecosystem. Without them parasitic wasps will not have food and would not survive. So keeping a few pests means success for their predators as well.

Blower motors are rarely easy in most cars. It wasn’t great in my 71 BMW either. But I recently had the pleasure of replacing a battery in a 2017 BMW X1 and that simple task took me 6 hours. Maintenance on new cars is ridiculous. I love this guy’s simple approach to happiness through anti consumerism. It’s definitely a goal for me.
Leaving aphids alone to help encourage a crop of ladybugs for the future.
Agree. MS arc works great after a little time getting used to it. I much prefer the flat shape for packing.
Wise words. More people need to think and chill before unleashing.
Actually, the bell is because their horns don’t work.
Very appropriate "Tutto passa" tattoo
