My L7s have a lot of padding in the ankles, and my Vapors seem to have next to none, but it may just be because they're pretty broken down. The actual width of the heel seems to be pretty close, but the missions are an EE and the bauers are a D. The Missions also feel a bit deeper, which may make for more problems with heel slippage if you don't need a high volume skate. yeah i was never in love with mission ... id just love to hear feedback on if other people have had the same issue as me with the xxx's and whether or not the 9k pumps would be a wise or poor option. those are the skates im really leaning towards
