Fortunately these are not too too big so I?m planning to put another pair of insole :) Purchased October of 2017, lasted only until about May 2018 before the soles began to rip apart and wear thru. I highly recommend these to anyone with back/leg/foot pain as well. Didnt know much about it but the price was right. I had to settle though because so few quality baby shoes come in simple white. 5 in US; a 9. The toe box is a bit wide but the heel is snug allowing my narrow size 10 feet to feel perfectly comfortable. I don?t necessarily know if it?s helped with the dramatic hourglass frame I aspire to have, it?s hard to tell with a decent amount of junk in the trunk already. I?ve also thrown out the packaging so I can?t return them. And now at 10 months they are dead.
