Yes indeed! That is the good stuff right there.
Kidsan,
This forum is a place to ask any questions you may have, now starting out and as your practice develops. In classes, talking with other students and just about everywhere you look online, you are likely to hear or to be directed toward many different (and opposing) things within the context of Yoga practice; cute little toe polish separators may just be the beginning. I want to encourage you to try the things that you have a pull towards, and at the same time, to experience all the subtle joys that Yoga asana practice has to offer to YOU, because of your unique and beautiful body. For me, it feels so good to create a strong foundation for my postures through the opening of my feet, from my toes to my heels. It is such an integral part of each posture for me and my feet have changed in the years of my practice, becoming internally stronger, my toes open wide and comfortable, my feet are awake. I believe, as a Yoga therapist, that toe separators are unnecessary for practice and I know for myself, as person with an asana practice, that it would have distracted me from really experiencing my feet during practice.
Something to maybe also consider, is the joy you are experiencing in your feet after wearing the toe separators for the evening is your feet and toes “waking up” to the attention, care and awareness that your are now offering them. Maybe the separators are secondary? Only the toes knows!
I hope this is helpful in regards to your question.
Namaste
