As your child grows, you can easily adjust the 15-position no-rethread harness and headrest with one hand.

Difficulty
Size: 11, Color: Classic Penny Loafer-802-black
I’ve had these shoes for a few months now. When I first got them, they were very painful to wear. I was wearing them pretty much every day but found them to be extremely tight. I thought perhaps the shoe just had to “stretch“ and conform to the shape of my foot, so I decided to give them a few weeks to do that. After a few weeks, they were still somewhat painful to wear. It was only until just within the last month or so that they have become painless to wear. So please be aware that you might find the shoes to be very uncomfortable when you first get them. Give them a chance to stretch and adapt to the shape and contours of your feet, though. The shoes are extremely lightweight and very flexible and bendable. They almost seem cheap in that regard, so I’m not sure what to make of that. I’ve never had a pair of shoes like this that were so flexible. I’m used to having a hard, rigid sole and an inflexible upper. The shoes do look very nice and seem to be holding up well. People have complained in their reviews that the stitching at the back on the heel comes undone. I haven’t noticed that with mine — yet. That is the only part of the shoe that doesn’t seem to be designed very well. Why put stitching in such a precarious place on the shoe? This is the first shoe I have ever seen that has stitching on the heel like that. But, as I mentioned, my stitching is NOT coming undone like many others have reported. PROS: 1) The shoe seems to fit comfortably after a couple months of extreme discomfort. Still not the most comfortable shoe overall, though 2) The shoe looks nice! CONS: 1) The shoes seemed very tight when I first got them and stayed that way for a couple of months thus ensuring extreme discomfort and pain when walking in them. 2) The stitching in the heel is a bad design! 3) Due to the shoes being extremely lightweight and flexible, they almost seem cheaply made. RECOMMENDED WITH HESITANCE

Nice-looking shoes
Size: 7.5, Color: B-black
I really like the look of these shoes. They can be worn for more casual look or more dressy look. When I first tried them on I considered returning them because they were a little tight in the width. I wore them for the first time today. After only 2-3 hours of wearing them I could tell that they stretched some and weren’t so tight across my toes. They were comfortable too. I am generally not hard on shoes so hoping they will hold up well.
