I have got the SL22 boosts, we have our first outdoor session tomorrow so I will know how good they are on a pretty wet outfield. Our ground is what you might call basic, so if they are ok on that they will be pretty good during the rest of the season. I'm a keeper if my name wasn't obvious. Can't see fast bowlers using them but others might be fine.
I've had to get a size 12, I'm usually an 11, as I have pretty wide feet. I was wearing them around the house like the loser I am and and found them so comfortable.
Now I've talked them up I will report back too.
