Soft Footwear for My Parents

My parents are in their 70s already and they are still very active. They always go to our farm and enjoys walking. I am looking up for soft footwear I can give them so their feet and legs will not hurt everytime they will have a long walk. I saw this Naot footwear that is suitable for outdoor and active lifestyle because it is very soft and light. I am planning to get them a pair each so they will be comfortable when they walk going to our farm.
