I cannot say enough good things about these wedges. It seems sturdy. Veniamo ora alle impressioni durante il volo. ha ha. All in all, Im happy with the purchase. It also worked great. As I find a need for additional hooks Ill be buying more of these. I bought this to use when working out. I decided on this shoe because the wedge didnt seem that high, I like shoes with ankle/heel straps in this style, and I figured Crocs would be comfy (never really worn Crocs before). Based on price and wanting to try out the optical switches, I thought this would be a good option.
