Sole: 6 mm light flat Vibram® Superflex. Vibram® are leaders in manufacturing of soles and sole materials. The Vibram® rubber products we use act as a natural shock absorber and have excellent non-slip characteristics. The soft, highly flexible and elastic soles provide a surface contact which stimulates the foot receptors and assures proper and healthy foot development by promoting a maximal barefoot feeling.
Shoe width around the ankle is regulated with a velcro strap (hook-and-loop fastener).
Appropriate for outdoor use in kindergartens, yards, sandboxes, etc. This model has a large toe box which helps the thumb to assume the best position for the body weight to be taken in.
HOW TO DETERMINE THE SIZE: Print the sizing chart for this model here.
If you do not have a printer, use the instructions and the sizing table below. Measure the feet as described here.
The inner dimensions of this model are described in the table below. The foot length should fall within the range in column "RECOMMENDED FEET LENGTH". The circumference around the widest part of the toes should be close to the numbers written for each size in column "MAXIMUM CIRCUMFERENCE (TOES)".
Important: "USABLE INNER LENGTH" described in the table below is equal to the length of the inner sole as shown in the photo on the left.
* Width: Please choose a width option from the drop-down menu. In column "MAXIMUM CIRCUMFERENCE (TOES)", NARROW width is "-5 mm" and WIDE width is "+5 mm", as they concern the leather part width only and not the sole.
Column " SHOE WIDTH (TOES)" is for your reference only. Currently, we do not customize the sole width.
