I don't understand the hype and marketing around insoles for impact protection, talking to podiatrist's and industry homies the insole is for support (helps prevent lower back pain with arch support etc) but the actual impact protection is from the outsole of the shoe. Just annoys me to see snake oil style mis-marketing that relies on placebo, like a better insole on a thin vulc may feel better and make the shoe way more comfortable, but it wont actually result in better impact protection...
