now that I'm looking at them, I think the ones I have are the 590, not the 300 DES. Here's a link for (I think) the one's I have. If you're gonna buy a pair I suggest sizing down at least a half size. I'm usually a 13 but mine are 12 and fit well > http://www.amazon.com/Belleville-590-Combat-Tactical-Olive/dp/B00915VK40/ref=sr_1_9?ie=UTF8&qid=1448493770&sr=8-9&keywords=belleville
never heard biscuit used in that context, but I did some research and they're not 300s, they're Belleville 590, like $130 or so > http://www.amazon.com/Belleville-590-Combat-Tactical-Olive/dp/B00915VK40/ref=sr_1_9?ie=UTF8&qid=1448493770&sr=8-9&keywords=belleville
