My little girl is 1 year old, I initially ordered size 20 boots and they were big, I asked for a replacement and they arrived the next day. Very prompt! The girl was born with her left leg slightly held inwards and totally refuses to walk even after physical therapy, no sustained walking, no steps. Total refusal. Since I put on the boots, total shock, in just two days it walks and treads perfectly and is held only by one glove. I didn't think I'd see anything like that but it's absolutely wow. I wholeheartedly recommend, we will return with orders. Thank you! You rock! ❤️
