nice idea but, IMHO, unless your hiking in snow, both tall n short gaitors are over-rated and hold in too much heat and moisture…
i think it would be a very limited market.
i would however like to see someone make a gaitor out of a material like ladies black stockings… just a tube you would put on before your boots then pull down over top of boots. they would weigh almost nothing, keep debris out of your boots, and would allow heat and moisture to excape. in 2000 i met a hiker in the wilderness who made his own gaitors out of stockings like i described… and swore by them… dunno how well they stay down over top of boot or shoe… might be something to work on
