@pie Arent they though? Hiking boots are divided into class A, B, C, and D with numbered sub classes.. So you have things like class B, subclass 3. I think anyone who is really into buying quality shoes/boots other than just "it looks cool" will probably know what class they want.
In addition to that there are specific manufacturers for the soles that many shoes advertise that make a big difference. For example I always get shoes that have Vibrams soles rather than generic soles.
Then there are the different classes of insoles I suppose but thats more brand and marketing than an objective measure I guess.
@pie Well it is somewhat focused on hiking but not entierly.
For example sandals are class A, and class A2 is more durable than class A1. I'd consider sandals day-to-day shoes. But yea the classes are hiking oriented in the sense of "how well does the shoe hold up to rugged terrain", but I'd say to some extent that would carry over to every day shoes. with that said I think shoes that you'd never use hiking (like a true g-string style sandal) wont have a rating and its more outdoors sandals youll see getting the rating.
Me personally I only were these style of shoes cause in my mind hiking isnt really that different from day to day wear. A class for my sandals and light shoes, B for my every day shoes, C for my high quality hiking boots.. I have D class too but rarely wear them unless im doing actual hiking on rocky terrain, and its overkill for that most of the time really.
