To use this calculator:

1. Select a kids’ Nike size from the dropdown menu.
2. Click the “Convert to Men’s Size” button.
3. The equivalent men’s Nike size will be displayed.

The conversion is based on your chart, covering kids’ sizes from 3.5Y to 7Y and their corresponding men’s sizes.

Key points about this conversion:

1. The conversion from kids’ to men’s sizes is straightforward in this case, as the numeric values are the same (e.g., 3.5Y in kids’ is 3.5 in men’s).
2. The calculator only includes sizes up to 7Y, as that’s the highest kids’ size provided in the chart that has a direct men’s equivalent.
3. For sizes above 7Y, the conversion might not be as straightforward, and it’s best to refer to Nike’s official size charts for the most accurate information.
