Yeah, padding can be dangerous but it's tough to let go. When I run, I flip upside down and use my shoulders the way most people use their feet. So, to give my shoulders some support, I bought a bunch of padded blazers. They feel great now. I can shoulder-run for miles without any aches. But my doctor warns me that the padding that felt so good for so long will ultimately give me arthritis or even a hunched back. I started experimenting with unstructured jackets instead, and though there's more pain in the short term, I feel safe knowing I'm saving my shoulders from a darker future.
