Where do I label my combat boots Marine corps? I do not understand the order...?

In MCO P1020.34G it states Shoes/Boots. Inside, near the top.......... does that mean on the inside of the boot near the top... or facing inwards near the top of the boot??? I was told two diffrent things.. I was told left side of boot on the top... inspections monday please help... yes this is cammies.
