A wellbore system includes a sealing assembly for creating an annular seal between wellbore members. The sealing assembly includes a wicker profile defined a first sealing surface for engaging and embedding into a radially adjacent, second sealing surface. The wicker profile includes a first section having a first hardness and a second section adjacent to the first section and having a second hardness greater than the first hardness. Both the first and second sections of wickers are embedded into the second sealing surface, and can thus provide a high degree of both sealing and lockdown performance.
