Alongside, fit the toe bar beneath your toes comfortably. 

Step 3: Keeping Adequate Space

Upon fitting your feet inside the shoes, you need to buckle all the straps. Remember, these buckles shouldn’t be too tight at all; rather, it needs to be snug. Most people think that the support they need while walking or running will come from the tightly buckled straps, but it’s completely wrong because the footbed gives the help we need.
