The three-quarter length and trim profile of this men's removable insole make it appropriate for a range of tighter-fitting business, dress and casual footwear, redistributing weight across the foot, absorbing impact, improving alignment and helping to reduce blisters, hot spots and fatigue. The energizing, biomechanically shaped Superfeet Delux Men's Dress Fit ¾ insert is easily swapped between different low-heel shoes that lack adequate support. Life is too short for unhappy feet!
