I'm advised that if you reverse them, so that the conical bits point outwards, they're less likely to catch your heels.
If you want proper roll, a pair of eazy wheels is around £12.00 from £vans - given that their real cost is probably 25% of that, I don't know why they don't fit them as standard to, as you say, a thousand pound bike, and be done with it. Those default wheels do little other than let down an otherwise great (never thought I'd find myself saying that about a Brompton) bike.
