The list Explorandes gave to us was excellent. Key items for us were hiking boots, poles, layers for clothing as the weather does change, mitts and a toque, and extra socks. A headlamp or flashlight is also of benefit. Enjoy your trip!

Toilet paper, rain gear, walking poles, good shoes, double socks, layered clothing (merino wool or any non-cotton fabric) and battery charger for phone/photos.

The company does provide a list of recommended items. Good rain gear and rain pants are necessary as well as hiking boots and socks that you have worn in. Also consider seeing you physician for high altitude meds which you need to start prior to leaving. In addition spend time at the gym using the stairmaster to go up hill and down hill. Try to arrive in Cusco at least two days prior to departure to acclimate.

Explorandes give you a very thorough checklist when you book with them.

I wouldn't really like to use to word 'essential' as every bit of kit will help you, but if I had to do the trail again then the one thing I definitely wouldn't do it without would be a very good pair of hiking boots with ankle support (I lost my footing a few times and my boots saved me).

Walking poles, sun lotion, insect repellent, sports underwear (or at least vaseline to avoid chafing) and fast drying layers (not cotton) are all important too, in my opinion. You're walking long distances every day. The last thing you want is to be wearing uncomfortable clothing or have itchy bites or sunburn irritating you.
