@literally45-- I'm against the use of socks in yoga. There is just no need for it and in order for yoga to be beneficial, I feel that bare feet must touch and feel the ground. This is something that helps balance and when the soles of the feet have contact with the ground, energy is neutralized. If someone has trouble with balance postures, this is a sign of an overactive mind and can be overcome with practice and meditation. Special socks are not the right option.
Yoga has been practiced in Asia for thousands of years. And those who practiced it did not have special equipment like mats and socks. They would practice in nature, on the ground and barefoot. This is still how most Asians practice yoga.
All of these equipment for yoga are just a way for manufacturers to make money. In reality, none of it is needed.
