"Standard issue special forces 4th Millenium Combat Boots."
HVM Combat Boots are boots from the HVM Kevlarseries made by HVM. They are the worst boots in the game, but they are still pretty good for the first 5 levels or so. The version can be decent for mid-game, and the version is nice to have until a suitable replacement is found. As with all HVM equipment, replace it as soon as possible.
These boots don't match the rest of the set because: 1. They aren't green, and 2. They aren't said to be made of Kevlar.
