Can your running shoes go in the wash?
There are good and bad ways of keeping your runners looking good

At this time of year, if you’re running outside, your spiffy new running shoes might be looking a little the worse for wear. With early spring weather come slush, salt and grime, and if you want to keep your shoes from staying grubby, you might be wondering if it’s OK to throw them in the laundry. Most brands will advise against this, since it may damage the technical materials in the shoe (not to mention your machine), but there are safe ways of cleaning your shoes and keeping them looking good.
How to clean your sneakers
First, it’s best not to put them in the laundry; but if you insist, you can remove the laces and insoles and wash everything on the delicate cycle. (Put the laces and insoles in a mesh bag, so they don’t get tangled up with other items, or stuck in the door.) Throw a couple of towels (or a load of laundry) in with your shoes, so they don’t damage your machine.
Never put your running shoes in the dryer, though; the hot air is damaging to the materials used. The best way to clean your shoes is to take a stiff scrub brush to the midsoles and outsoles (use a little water, if necessary) to get rid of any mud or surface dirt. For the uppers, use a moistened soft brush (such as a toothbrush), with a drop of mild detergent (such as dish soap) to clean them and remove salt stains. You can also use a wet cloth on the uppers. You can rinse them under running water, then squeeze them in a towel to absorb excess water. Then stuff them with tissue paper or newspaper and let them air dry (not in direct sunlight).
Good as new!
