Detailed post I must say. It's interesting to know that you prefer walking barefoot especially on the beach side. This is very much cool to me. Wearing shoes is also integral to avoid parasite and infections from getting into our body as our bodies are very sensitive to ecto parasite. The hard feet many has and the scaly part of the feet is as a result of not maintaining the feet by moisturising it daily. I do apply feet cream so my feet can be soft when wearing shoes. You wrote a good content. Looking forward to reading more of your posts
