Fashionable Converse high-tops may be comfy enough for walking around town, but you’ll need a supportive pair of trainers to get you through your workout pain-free. “Find a shoe that works for the type of activity you’re doing,” recommends Kathleen Trotter, a personal trainer based in Toronto. Cross-trainers are fine if you’re working out on the weight machines, but runners should be fitted properly at a specialty shop like the Running Room.
