the above Gizeh footwear is a version of flip-flops specially designed for people with a narrow, slimmer foot (two types of width are distinguished in Birkenstock footwear)
The secret of Birkenstock is certainly the anatomically shaped insole that adapts perfectly to the foot in accordance with its natural arrangement
under the toes and on the midfoot there are protrusions, while under the heel there is a recess, thanks to which the foot is always in the right place, which ensures full stability and balance
such profiling strengthens the calf muscles and stimulates circulation, so we can wear footwear for many hours and it will be safe for our joints
