I think sensation paths would be a nice addition to parks as a way to make it a little more than just grass, outdoor gym equipment, and concrete pathways. In fact, since the USA does like getting many of our ideas from Europe (most specifically from Great Britain/England), some European countries have parks, called "Barefoot Parks", that allow people and children (of all ages) to publicly explore and innovate to nature. Here is a link if you want to read a little more about some of the popular barefooting parks in European: www.barfusspark.info/en/park.htm
For those who love going/being barefoot, there are in fact over 50 different health benefits to going/being barefoot. Some of the floorings (with each space must have a border around it) you can choose for the path, like synthetic grass or wood or even hay, are technically not going to really become hotter (due to its material) when in hot weather unlike cemented concrete (the common pathways) in the summertime and even in sometimes in the Spring or Fall depending on the city. At the same time, creating sensational paths would help you save less money than if you were to create the regular concrete paths.
If someone really likes the idea at the park to make it a little more colorful and innovative (in terms of the sidewalks and walkways), it can even be to the point where some may want to learn how to create one in their backyard or even as the main walkway in front of their house.
When it comes to science museums, they are basically for the teaching people something new based on the science of something or someone. So, in terms of scientifical health, they should have a section in science museums dedicated to the science of barefooting (along with the fact it's legal to be barefoot in public).
One way that it can be implied in science museums is creating a sensational pathway as if it was a human board game like "Chutes and Ladders" or "Candy Land". Letting a sensational path in the style of a big board game would be a nice method for when it comes to getting people more interesting in barefooting while learning something new, along with the truth about barefooting, at the same time. Since it is inside the science museum, each pathway will be in great condition in terms of temperature and the fact that each pathway block will never overheat.
For those who are blind, you can have rope and/or handrails for them to help them navigate through the pathway. Here is a simple link on how to create a sensation path: www.barfusspark.info/loesungsk/fuehl_ausfuehr/fuehl_ausfuehr_en.htm
