woman size 6 boots/kids size 4-5 (Mississauga)

I am visiting family in Mississauga until Jan 27. In need of black, navy, or grey winter boots, slip on or zip up for easy on/off.
Good thread needed for safe walking to the park or going to the school bus.

one of the zippers of my boots is not working properly, and not safe on ice.

Close to Applewood neighbourhood would be a bonus. Near Mavis, Dundas, Burnhamthorpe, Dixie/Bloor.

Thank you!
