These are the most comfortable boots I have ever worn (next to the Magnum Sidewinder HPi review to come). They are very lightweight (22 oz on my scale). and wear well so far. These are a quality set of boots that will set you back about $120 or so. Not a bad value considering what you get for the money!
Clarification from Magnum:
Magnum does have insoles for sale under accessories section on the website (http://www.magnumboots.com/us/boots/accessories/) and with most of their retailer partners. Also, they have listened to the consumers and will be replacing the laces of the Spider Urbans from here on out.
