The best way to determine the correct size is by measuring your little one's footprint.
To accurately measure your child's foot. Place a piece of paper on a firm flat surface (book, table, tile floor, etc). Have your child stand, or press their foot firmly onto the paper. Draw a line at the heal and the longest point of the toe. Measure the distance between the lines on the paper. Find the measurement on the "Child's Foot Length" column on the size chart to find the correct size. Size charts are found in the photos and item details of every listing. I recommend measuring in centimeters for better precision/accuracy. It' s very easy to misread the measurement in inches.

All shoes may be machine washed in cold water with like colors and air-dried. Use a phosphate-free detergent. No Bleach.
The non-slip rubber can be wiped down with a wet cloth for quick cleaning.
Briefly soaking in lukewarm water and dish soap will help remove more stubborn stains and odors.

Right now we are only offering shoes as they are shown/offered in the listings.

Some of our organic and eco-canvas shoe listings have lining options. Here's our suggestions of what to choose.
**Very Soft OBV. This is out softest and most cozy lining option. Made from OKEO-TEX certified Organic Cotton and Bamboo, there is nothing softer. Perfect for year round use, but can be a little warm in hot/humid summer weather. This is our personal favorite.
**Organic Cotton Velour. 100% GOTS certified organic cotton is a soft plush velour, great for year round use, but can be a little warm in hot/humid summer weather.
**Organic Cotton Knit. This is the favorite for summer and sweaty little feet. It's thin and smooth like a t-shirt, but super soft. Made of 100% GOTS certified Organic Cotton.

Yes, the non-slip soles are water-resistant and made to withstand some light outdoor use. They might not be the right shoes for everyday outdoor play, especially in older more active children. Little Pitterpat shoes are thin flexible and super soft to mimic going barefoot. As is the case with any super soft sole shoe, rough surfaces like pavement, asphalt and rough playground surfaces will wear the shoes out quickly.
