Introducing Perfect Pump. Pumps that work as hard as you do. Launching 1/31, 12PM EST. Pumps are a versatile heel that are typically worn for long periods at a time. We carefully crafted ours to work hard WITH you, not against you. Majority of pumps on the market are stiff, hard and uncomfortable. We designed our pumps to be made with ALL soft/flexible (and vegan) materials that have stretch and “give” instead of being stiff and hard.  Features:  4" heel with a wider base (provides more stability), synthetic patent PU  leather, latex insole (easier on the feet for long wear), cushioned insole, non-slip rubber sole Sizing: If you have a narrow foot, order your true size. If your foot width is regular -wide, it may be best to go up 1/2 a size.
