Hey there! Based on your question asking for a high school product for a big child size 7, I'd recommend either the Girls Black Baby Doll School Shoes Size 2-7 for R379.99 or the Fullmarks Missies T-bar Girl Black School Shoes Size 2-7 for R159.99. Both of these products seem like great shoe options for a big child in size 7 going to high school. The Fullmarks pair is more affordable at under R160. I hope these shoe suggestions are helpful as you gear up for the new school year! Let me know if you need anything else.
