ZigzaggerMen's Zermatt Wool-blend Loafer Slippers with Memory Foam Indoor

Do these stretch out after being worn? My hubby has narrow so they need to stay on his heel! Will that be a problem?

I want to know from somebody who's had these a long time (6 months minimum). How long does the padding inside the shoe stay soft?

Will these fit a wide foot?

Do these come in womens sizes
