Hey, it seems the order in which you put on your stealth-modifying gear affects the effective stealth value.
In this particular case the behavior happens with a balaclava (+stealth) and strider boots(-stealth).
Balaclava, then boots: 0 stealth.
Boots, then balaclava: > 0 stealth.
This character has 0 skill points invested into stealth. No other gear was equipped.
See attached images for details.
Cheers.
