Q. I was wondering when one touches his shoe or covered areas of the body with only one hand, does he have to was both hands as when one goes to the bathroom? This seems to be important on Yom Kippur when one must avoid unnecessary washing.
A. Horav Shlomo Miller’s Shlit’a opinion is that one need only wash the hand that touched the shoe or the covered areas of the body. (See Kaf Hachaim 554: 73, Piskei Teshuvos 553; 3 and others, who rule that one must wash even for touching tennis or cloth shoes).
Rabbi A. Bartfeld as advised by Horav Shlomo Miller and Horav Aharon Miller Shlit’a
