Depending upon how sensitive his Glans is when exposed, he may find that by retracting the foreskin, he enjoys greater friction. I recommend that the Glans of circumcised men be lubricated just before putting the condom on. This gives it more wiggle room thus transmitting more friction.
I wouldn't think that the foreskin is a a contributing factor to the condom shifting. You can certainly test this by having him pull out ocassionally to have a look at what is happening. What is more likely the cause is that he is using the wrong size condom. Manufacturers offer them in three basic sizes so next time you are out grocery shopping check out the shelf of condoms and see if there is a better choice.
