not all autistic people "toe walk" but most of us have difficulty determining where our bodies are in relation to almost everything else, and this can show up in the ways we walk or move just in general. I tend to walk like I am walking on a rope, one foot planted straight in front of the other, and I often touch the door frames, furniture, walls, etc. I was constantly being told to keep my grubby hands off the walls, furniture, etc... I have always been afraid of falling. Stairs are particularly tricky and I used to fall up or down them a lot. Not so much now, I move a lot slower than I did when I was a child and accidents have taught me that is the best way to be safe, to be cautious ... I do still touch everything around me as I go from room to room, but my feet still hid chair legs, table legs, baseboards, etc. It is part of "proprioception" and almost all autistic folks have some version of proprioceptive struggles. Shuffling might be your version!
