Sturdy, I must say
Wao!!!. Did not know I could ever find this after almost 14 years since I last used it. Bought these for ALL my footwears. It does balance the soles of a shoe, helps to alleviate all those one-sided slopes of shoes after a while, and increases the life span of the soles....from my experience.<br />Going to three weeks since I purchased these and till now, no signs of wearing out yet on them! Sturdy, I must say.
