Haflinger AT Hard Sole Slipper vs Haflinger ATB Wool Slipper

Both are Haflinger boiled-wool slippers with latex arch support and rubber soles. The AT Hard Sole is the lighter, simpler slip-on with a fixed wool footbed; the ATB has a removable cork-and-latex footbed, a closed high back and decorative trim. Owners of the AT line praise warmth, breathability and arch support, but some report holes near the toes within a year and wool that mats down. Buy the ATB if you want a replaceable footbed and a more secure heel; buy the AT Hard Sole if you want the classic low clog and a lighter slipper.

• Choose the AT Hard Sole if you want the classic low-back boiled-wool clog that is light on the foot and easy to slide on.
• Choose the ATB if you want a closed high back that stays on your heel and a removable cork-and-latex footbed you can air out or replace.
