Shoes Off, Please by Ronnie Citron-Fink

I am as neurotic as the next person about keeping my floors clean. With dogs and kids, the inevitable mess happens. The kids are trained to take their shoes off. The dogs know that if they wait on the mat while their feet get cleaned they will get a treat. And my guests are kind, gracious and accommodating – they usually offer without being asked.

The practice of taking shoes off can be found throughout Asia. It is also common in Scandinavia and in Hawaii and Alaska. In Japan, many homes have a getabako, or shoe cupboard where shoes are stored. Taking shoes off is a symbolic gesture that leaves the outer world behind. Shoes are traded for comfortable slippers and home becomes a separate sanctuary.

Recently, my husband and I stayed at my brother’s ski house in Vermont. Not only are ski and snowboarding boots clunky, it’s mud season in the Northeast and those boots make an incredible mess. My brother and his wife have a whole room dedicated to shoes/boots/ski stuff. It is a neatly organized mudroom that provides a barrier between the outside and the inside with storage for lots of stuff. Architect Susan Susanka, the author of the Not So Big House books, is a big fan of dedicated mudrooms for encouraging friends and family to take their shoes off when they enter a home. A mudroom is a perfect place to leave those shoes behind while providing all the elements for a cleaner, healthier home.

5 Reasons To Take Your Shoes Off

1. Keep your family and pets safe from outdoor pesticides and pollutants that can contaminate carpets and floors. The EPA found that pesticides on shoes are considered to be a major source of toxic exposure for children.

2. Improve the indoor air quality. (Join the Moms Clean Air Force to find out more about keeping your family safe from air pollution.)                

3. Spend less time cleaning and consume less cleaning products.

4. Keep your home quieter.

5. Save your wood floors from dirt and rocks that can create gouges.

Do you have a “No Shoes” policy at your home?

Shoes Off: Just Do It! by Jan Devereux

Growing up in Florida with the beach virtually my backyard, I spent a good deal of my childhood barefoot — outside and inside — so maybe that’s why having a shoes-off policy in my own home feels completely natural. I now live in New England, where “mud season” stretches well into April and almost every house has a mudroom and a pile of boots near the door. ‘Boots off’ is the norm in my neighborhood.

But even if you’re lucky enough to live in a place where it’s flip-flop season year round, a shoes-off policy is an essential step in protecting your family from germs that can creep in on the soles of your shoes. “Dirt” tracked in endangers more than carpets. Residues from the lead in car exhaust, toxins from lawn pesticides, traces of animal waste and allergens like pollen on the ground all present a health risk, especially to small children and pets that spend time on the floor. You don’t have to be neat freak like Monica from Friends or a germaphobe like Monk, the TV detective, to care about these risks. Removing shoes at the door is simply a matter of good hygiene, like hand washing.

So why do some people resist setting a shoes-off policy, and why do those who do feel they have to tip-toe around enforcing it with recalcitrant guests?

Remember the Sex and the City episode (“A Woman’s Right to Shoes” Season 6, Episode 83) when Carrie attends a party, and the hostess (Tatum O’Neal) makes her leave her brand new $485 Manolos at the door — and another guest walks off with them? Carrie is outraged, not only by the theft and the hostess’s refusal to reimburse her the full price of the shoes, but by the imposition: “It wasn’t my choice to take them off,” she whines to Miranda.

To avoid such shoe drama in your home, why not give guests a shoes-off heads-up in advance? And greet them at the door with a basket of socks. This might even be a great way to re-purpose orphan socks from your laundry. If you have slippery floors or uncarpeted stairs, you might want to stock up on socks with rubberized treads for safety. And if you still encounter resistance…well, in my opinion, a guest who doesn’t smile when offered a pair of mismatched, borrowed socks may not be worth inviting back!                                                                                                       And speaking of humor, I stumbled on a blog dedicated to supporting people who want help enforcing a shoes-off policy. (shoesoffatthedoorplease.blogspot.com/) (I guess there’s officially a blog for everything by now!) In addition to the author’s wry posts on the subject, the sidebar lists “37 reasons why you should enforce a shoes-off policy.” Carrie Bradshaw, please take note of #29: “If you wear high-heeled shoes, your feet badly need a break.”

Jan’s product suggestions:

WJ Dennis recycled polypro boot tray (referenced on the site already under the action plan). Having a place to put your shoes means you will be more likely to remove them. This tray is made out of recycled polypropylene. It’s durable and affordable.

Traction/non slip socks in organic cotton (pictured above) from Amazon: “These non-slip low-rise socks are made from organic cotton with a reinforced and cushioned heel and toe! These socks are a a great hygienic alternative to bulky shoes — whether you are lounging around the house, traveling, or performing low-impact exercises such as Yoga or Pilates. Wear on the plane, in the hotel, or at Pilates or Yoga without fear of germs or fungus!” (Jan’s bolding)
