Pleasant Pumps has a non slip fabric and a unique foam cushion to the sole of the shoe that will conform to your foot over time. This will not only provide long lasting comfortable shock resistance, but better traction to keep the toes from being smashed against the front of the heel during long hours of wear. I’ve also incorporated a thin layer of foam into the lining of the counter (the area that supports the Achilles) to ensure the most supreme fit. This will keep the foot from slipping in and out of the heel. Combine this with an interior silk lining and the heel is practically blister proof.
