Nike Total 90's astro boots are good for both.... played on astro...trained on hard ground... used at Masters Utoxeter in pooring rain (and mud) and still stayed on my feet
nice and light and if you look around and get last years style get them for £20 - 25 quid
PS
i have pro-joy golf shoes as good as money could buy and they would be like playing in cloggs
for turf I use gold shoes and gras I use American football shoes. It was tricky at campaign since they used turf and gras, due to the weather I used the football shoes.
i just wear astro turf trainers, no problems at all., Yeah you could go for field hockey turf trainers, they're more rugged and designed for being hit by big balls and sticks, but i used my old astro's in both hockey and paintball and theyve done great for both, only cost me £15 in the local sport shop
I use some random moulded nike football boots.. they are fakes off ebay, but they have lasted 6 months so far and are still doing well.
Cost me all of about £12, and are bloody comfortable, and very grippy.
