Endurance style stirrups for big feet?

My husband would like some light weight stirrups. I currently have barefoot fenders on his English saddle - a 1" leather w/ a really wide fender in the front - because it helps him keep his leg off his horse.

I have SA Walls twister stirrups on them - but they are pretty heavy.

I was looking at getting some EZ Rides - but his shoes are almost 5" wide all by themselves!

Are there any lightweight wide footbed stirrups out there that anybody knows of that are comfortable for longer distances?

Tucker has extra wide foam padded stirrups. Not sure of the weight though.
