I've been a toe walker my entire life, so this is fascinating. Sometimes, this is indicative of cerebral palsy, but this isn't true for me. I'm not sure why I started to do it, but my parents said that ever since I was a toddler I have always toe walked—perhaps I simply like the feeling of my toe alighting on the ground first. Curious enough, my toddler now toe walks as well.
And I can confirm: my calves are huge, especially relative to my skinny frame. I also find sprint sports easier, like tennis and soccer.
Same aaand same. Started toewalking not long after I was able to walk, and I'd unconsciously stand on my toes when just standing idle for some reason. I replied in another comment chain, there was a link to wikipedia [1] that also linked to autism. I'm fairly sure that it's just one of those things that doesn't need to have a medical reason though. Especially not when hipsters do it due to barefoot walking shoes and such :p
