I'm on my second pair of the Hush Puppy Lincoln Slip on. Our first pair was a kid's size 10 1/2.  They are made on the large size and fit my little boy when he wore a 10 1/2, an 11 and an 11 1/2 shoe size.  We wear them to church or any dress up event that needs a brown shoe.  I picked them out b/c I LOVE that rich brown/maroon leather. They are shiny and look sharp.  He had a groth spurt over the summer and he now wears a 12 and 12 1/2 (depending on the shoe.) I ordered a size 12 1/2 thinking I can get another year and half of use out of this shoe.  The 12 1/2 stays on (he doesn't walk out of it)and he has plenty of room to grow.
