Same problem as another Globe Saber review. I used to have Globe CT-IVs and loved them. When I first put them on they were amazing. But the sole quickly stuck badly to the shoe on the heel and after 3-4 months a large crack formed in the transparent plastic, which formed an air cushion for the shoe cushion. . Since then I hardly wear them anymore because they hurt my heels too much. Pictures sent to Globe via her Twitter account, but no response. Very bad customer service. Conclusion: I will never buy Globe skateboard shoes again.
