Kid's / Toddler Speedo Water Shoes size Large 9/10

Kid's / Toddler Speedo Water Shoes size Large 9/10 These were worn 5 times at the most. Unfortunately, during a water play day at school they used chalk, and I have not been able to successfully remove all of the chalk (Most noticeable on the soles of the shoes). *Listing lots of my kid's stuff; bundle and save!* All proceeds go towards a Disney Cruise for our daughter!
