2 pairs of Columbia boots, read on (Old Ottawa South)

ladies, say sz. 9 and 9.5, are the same size, for the same person, maybe for snow shoveling ? my daughter is very hard on inside back heels and both of these boots were professionaly repaired at least twice each, it does not survive with my daughter, they are warm and comfortable but damaged inside, if someone wants to try these derelict boots for some outside work ?
