These flat sneakers features a soft comfortable rubber sole, a canvas knitted crochet body with stretchable elastic that easily slip on! The laces are just for looks, you do not need to tie these shoes as they stay in place. They are super stretchy and comfy! If you are between sizes, size down for the best fit! April usually is between a 9 and 10 (almost always closer to a 10) and the 9's fit her best.
