And I like these. They seem to be shaped with some thought, rather than the usual squares. Notice also how far forward the boot is placed. The weight is at the forward portion, which sinks deepest, The tail end is more easily lifted after the stride, breaking suction. The tails are also narrowed, and the rope bands are very far forward. These are thin ply, and looking at how they stack, it doesn't seem like they have cleats on the bottom.
