Decent conversion kit, but make sure you tighten the bolts fully!
"Bought these to convert a new pair of Fizik shoes. They work well and are very good quality, but do make sure you tighten the bolts fully. I thought I had but 30 miles into a sportive, I found I couldn't clip in - both cleats had come loose. I'd lost one of the two bolts in one shoe too. There is a torque specification for the bolts and it's important you measure this. Managed to borrow a multi-tool and finished the sportive!"
