The Gabby 1 Lace Up in Jeans from Ganter.

A clean, simple elastic cord (interchangeable handle) with a super flexible and soft sole. In addition, internal shock absorbers have been attached in the heel and ball area.

• Interchangeable footbed was developed in conjunction with leading specialists strictly according to anatomical aspects and guarantees a custom fit.
• The anatomically shaped Vario interchangeable footbed relieves the joints and strengthens the muscles and can be replaced with individual inserts.
• The patented shock-absorbing 4-point sole allows the foot to roll naturally. Just like walking barefoot. 
• High-quality vegetable-tanned calf leather and real cork are used for lining and footbed.
