The only LeBron shoes I've ever tried were many, many years ago, his early shoes, zoom LeBron 2 and 3. Both were heavy as hell, hard as a rock, not comfortable, and felt to tight in my usual size even, it was like walking around with bricks on your feet. The only Kobe's I had were the Adidas KB8 (really comfortable), Adidas The Kobe (huge, built like tanks, but somehow also comfortable, and even moreso when broken in), and the Zoom Kobe 1's (which I thought were awesome). These days I play in whatever quality, light, low top running shoes I come across at the thrift store ha ha.
I'm not sure someone with catastrophic lower leg injuries the last two years has much room to trash talk another shoe.
