HAFLINGER Womens Charcoal GRAY Classic “GZ” style Comfort Winter Germany Wool Slippers (retail $155). Nice arch support & a rubber-lined cork-blend sole. Warm & comfy!

Size not indicated, but these fit me perfectly - I wear 8.5 (so, between at 39 & 40). Of course I can’t be certain, so please measure the sole of your existing Haflinger slippers to compare - these are 10.5”.
