Heh, you're right, mate! these are improved replicas of those swiss gaiters - same pattern, different type of leather plus gears. This design is truly magnificent - it fits most sizes and looks very cool.
Well, I thought about that already, however there is some major problem with that - since craft is my main source of profit, I must think about affordable price for the item - and since making knee-long gaiters will take much more material and also more work time - the price will be higher, hence making gaiters like that less affordable... But I will surely make high gaiters for myself
