I love the look, material quality and light weight of the shoe, but it has a fundamental flaw. The toe box fits perfectly, but the heel is too wide, so my heel floats around and shifts sideways as I step, making the shoe unstable. I've tried to overcome this by tying the laces very tightly, but it doesn't completely fix the problem. I can still fit two fingers between my foot and the inside of the heel, even when tied as tightly as I can tolerate. Frustrating, because I own five other pairs of Clarks (I love their shoes, they're all I wear at work), and this is the only pair that doesn't fit perfectly.
