Angelique your picture is great! You have drawn your invention very vividly, you are a great artist! I really like the Size-O-Matic calculator, it means your invention works for everyone and you can get the most perfect comfy fit! Recording your walking pattern is really interesting also, maybe an additional element could be that the camera counts steps too for those who like to keep fit? New shoes hurting your feet are the worst, your invention is a great solution! You have a great imagination Angelique, keep it going!
