The Angels Walk shirt has long been prized as a collectible. The Angels Walk shirts are worn year-round by people on the spectrum and their families, encouraging acceptance, tolerance, and inclusion for people on the spectrum – without using words. Since 2007, the Angels Walk for Autism has been a yearly advocacy event hosted by the Autism Society Philippines. The SMX Convention Center hosted the 2023 Angels Walk for Autism on April 16, 2023.
