I've only used old macs, and found them very good. Stayed on, no rubs and lasted really well.
A horse I used to ride used them. Hacked out on stoney tracks and fields for 40-60mins 3 times a week. He only had them on his fronts. Lasted about a year.
cavallo, they are soft to the horses coronet and pastern and they are lighter and they are easy to put on, I haven't met a horse yet who didn't just take to these straight away!
Easyboot glove, great boots, easy to put on and not bulky
not sure about wearing in field would have though it wouldve made horses foot sweat if worn for a long period of time :-/
i'd be interested too if anyone has any suggestions for boots suitable for turnout. I'm in week 8 of abscess nightmare, leaving him bare on that foot wouldnt work as he's so sore (flat weak tb feet!). he's currently wearing a Davis boot like a welly but his foot is sweating like mad, and now he's got thrush :-/
oh and hello! first post here!
