In reply to troglodyte:
Was trying a pair on the weekend - they seem a bit wider than the velcro ones, but the elastic tongue thing makes it harder to get a fat foot inside. Feels nice and snug once it's there, though. The length seems pretty similar - size 41 works for me in both - but I reckon that the lace-ups might not give as much on account of the P3 thing and the elastic inner. Just a guess, mind...
