Reference for Yevamot 206:5
א"כ מה ת"ל נעלו נעלו הראוי לו פרט לגדול שאין יכול להלוך בו ופרט לקטן שאינו חופה רוב רגלו ופרט לסנדל המסוליים שאין לו עקב
whence, however, is it deduced that anybody's shoe is suitable?<span class="x" onmousemove="('comment',' For the halizah of any other person. ');"><sup>15</sup></span> Hence was the term <i>'shoe'</i> repeated,<span class="x" onmousemove="('comment',' Lit., 'it was stated shoe (bis)'. ');"><sup>16</sup></span> thus indicating the suitability of anyone's shoe.<span class="x" onmousemove="('comment',' Lit., 'from any place'. ');"><sup>17</sup></span> If so, why was the expression, '<i>His shoe</i>', at all used? — '<i>His shoe</i>' implies one which he can wear, excluding a large one in which he cannot walk, excluding a small one which does not cover the greater part of his foot, and excluding also a sandal which consists of a sole but has no heel.
