Does the conclusion hold for overweight people? While I was sub-80kg my sneakers used to last years. Once I passed the 100kg threshold I noticed my sneakers get worn-out after ~6 months, just walking. Makes me afraid the same happens to my knees.
- jfengel 1y agoKnees are not foam. They are living organs. The strain is taken up by ligaments and muscles, not (just) cartilage. If you locked your knees out, you would have to take the strain in your cartilage. That would hurt a lot. More weight does put more strain on those ligaments, and that can result in an injury. And you do wear your shoes out more quickly, which causes you to land unevenly and puts lateral strain on ligaments not designed to take it. The results are repetitive stress injuries that can take some time to heal. But if you're practicing good form, increase mileage gradually, and (ideally) do some strength training, overweight runners can run forever.
