What is the Most Supportive Keen Sandal?

The most supportive Keen sandal for kids is called the Newport style. Let me show you the 2 reasons that make the Keen Newport the best sandals for kids with flat feet:

1️⃣ The Keen Newport features an EVA insole with an internal support mechanism that is anatomically engineered to provide good arch and heel support.

Take a look at the image below to visualize how the outsole of the Keen Newport sandal looks like. Do you notice how the sandal on the right (Newport style) has a more substantial outsole compared to the sandal on the left?

2️⃣ The Keen Newport style provides extra cushion and support right below the heels. When a child has flat feet, you don’t only support the arch, you mechanically support all of the pieces that make the feet flat, such as the heels.

The Keen Newport is not available in half sizes, it’s only available in whole sizes. This can get a little tricky since most families get confused as to what sandal size they should order.

Shoes can fit short, long, or true to size, and depending on how they fit, you need to adjust the final shoe size that you get for your child. The Keen Newport fits true to size, so let’s take a look at a couple of different scenarios that will help you identify which Newport size to order for your child:

  • If your child measures a foot size 10, you should order the size 11 to provide your child with the correct amount of growing room.
  • If your child measures a foot size 10.5, you should order the size 11 to provide your child with get the correct amount of growing room.
  • If your child measures a foot size 11, you should order the size 12 to provide your child with get the correct amount of growing room.

The Keen Newport comes with a washable polyester webbing upper so you can throw the sandals in the washing machine as often as you need it. Make sure that you use a small amount of detergent, wash on gentle cycle, and air dry.

Some families prefer to choose bright colors so the washing machine restores them to that “new” look. You will notice that the Keen Newport will look almost as good at the end of the summer as it did in the beginning!

Children with flat feet should wear supportive sneakers for most of the day, but this doesn’t mean that they can’t wear sandals during the summer. However, even if you provide your child with a pair of the Keen Newport sandals that I recommend, you should limit the wear to no more than 5 hours a day.
