I grew up always using gamgee and bandages on my ponies. (from the 80's) I learnt to bandage said ponies very early and was often asked to teach friends how to do it before I was 10!! My late grandmother always insisted we did this, for protection and support. Over heating legs we never even considered. If we even thought of using travelling boots, I think she'd have a heart failure. Maybe it's a generation thing?
Early 2000 I purchased the 'shaped leg gamgee/fibergee', and thought it was brilliant. My late mare was almost impossible to unload, she'd crash, bang and leap about on the ramp, so we felt it did it's job perfectly. She loaded perfect, and travelled very well though. Always bandages for return journeys to help tired legs.
Loaded other people's horses and ponies in recent years, a few wearing boots, one bandages and probably more naked. Personally, from previous habits I guess naked legs look wrong.?
