Know Your Footwear Size
After putting on closed shoes using the correct technique, it is essential to double-check that the shoe size provides the right balance of support and room.
How to Perform the Toe-Space Test
To check for a proper fit, always stand up fully with your full body weight on both feet. Feet naturally expand and lengthen under weight, so measuring while sitting will result in an inaccurate, overly tight fit.
Press your thumb down at the front tip of the shoe to check the space in front of the longest toe:
For Adults:
There should be approximately one adult thumb's width (about 1 to 1.5 cm) of space between the longest toe and the front tip of the shoe.
For Growing Children:
Because children outgrow footwear rapidly, aim for a gap equal to two of your child’s finger widths (or about one generous adult thumb width). This leaves adequate room for growth and toe spread without making the shoe so loose that it causes foot instability.
Avoid Buying Shoes That Are Too Big
While it is tempting to buy shoes one or two sizes too large "to last longer," excess length creates serious biomechanical issues:
Causes Tripping & Awkward Gait: Extra length forces the shoe flex point behind the foot's natural toe joints.
Causes Toe Clawing: If the shoe is too roomy, toes will reflexively "claw" to grip the sole, leading to muscle fatigue and calluses.
Performing the thumb-space test while standing fully weight-bearing ensures adequate room for growth and toe splay without compromising stability or causing toe clawing.
