I was in a walker, as was my sister, and we never crawled. No neurological impairment here! Though I do have a high instep and like to wear heels, not sure if that's related. I only have foot problems because my feet are huge, not because of a walker as my sister's feet are fine.

Also they were fab as you can push the child in the walker out the door and close it to have peaceful time, as I did with my sister.
