In the clip, Chontel started by placing the shoes in the sink and wetting the bar of soap before rubbing it on the sneakers.

‘From there you will massage [the soap suds] through — I didn’t even take the laces out, I’m that lazy,” she said

But Chontel assured that the process works “every time.”

Chontel first rubbed the Sard Wonder Soap on both shoes until they were ‘nice and soapy’

After dosing the sneakers in the soap, she threw them in the washing machine.

‘I like to add a scoop of Vanish powder. Put that in there and then toss it on a delicate cycle,” she said.

Some choose to put the shoes in a laundry bag to protect the shoes in the washing machine, but Chontel did not do that on this occasion.

When the wash cycle was done, the busy mom put the shoes out in the sun to dry, and they looked sparkling new.

Sarah Sweeney, founder of Sarah Sweeney Podiatryadvises the average person to change their shoes every six to 12 months — while marathon runners should change their shoes every three months.

This frequency depends on how often you train and the intensity of the training.

Ms. Sweeney said if your shoes start to rip, if you don’t feel supported, or if the shoes feel “loose,” it’s probably time to replace your runners.

Ms. Sweeney also warned that not replacing your shoes in a timely manner could lead to injuries.

“Improperly fitting or old shoes can lead to any type of foot or ankle injury, as well as knee, hip or back pain,” she said.

“Injuries include, but are not limited to, rolled/sprained ankles, tendinitis, plantar fasciitis, tendon tears, and even stress fractures.”

More so, unsupportive shoes can also lead to balance problems or the risk of falling.

Ms Sweeney said many will probably be aware of the effect shoes have on your toes and skin on your feet.

“You can get ingrown or thickened toenails as a result of poor running shoes, and you can get painful and unsightly corns and calluses,” she said.
