It reaches the whole tibial nerve pathway, not just your toes.
Neuropathy usually starts in the feet because the longest nerves are the first to suffer. The tibial nerve carries sensation from your entire sole, and it travels behind the inner ankle and up through the calf to get there. A boot that stops at the ankle only treats the end of the line. Ours wraps the foot, the medial ankle and the calf, so the light reaches the nerve along its route, not just where you feel the symptoms.
What to check: look at where a device physically ends. If the shell stops at the ankle, the medial ankle and calf never see any light, no matter how many LEDs are inside.
