Highland Regiments footwear during the Great War

[Jacques]

To the seemingly unparalleled knowledge of forum members regarding everything kilt or highland history related on this forum, i pose these questions; At the beginning of WW1, were the British Army Highland Regiments wearing black or brown shoes? Also, i have read online most soldiers throughout the British Army had two pairs of boots, black for parade and brown for field/combat. Is this true? Generally, what colour boots would soldiers of the highland regiments been wearing once they were issued with boots and putties? i ask because all the information i have gathered online thus far have answered the aforementioned questions; yes and no.

Thanks much
