I just removed the plastic spacers in the middle and voila, done. it did fit small as I thought it would. I have two kids and family spread out so we fly a lot so for traveling this will help with all the short stops and only a few minutes for charging. They were the same position when we mounted them last night. I emailed the seller and was offered an apology and a 50% refund. Theyre cheapie flats. 5 years, and I have to get an insole insert to push them to two years because the memory foam wears out! 5 to 7 depending. Will continue to purchase in other sizes as her feet grow. Straps are strong and well sewn.
