Clamping questions

Hey I recently bought a hard cable clamp. Before you say I should’ve gotten a cable cuff pro, I’m from the EU and they don’t have those here. My first question is if the one that I bought works fine too

Next I was wondering if toe shields are a MUST HAVE or if I can also just use a double folded piece of cloth with self adhesive tape around it or something else. If so does this elevate the risk of injury compared to just using toe shields?

Last question if you make sure you don’t go too long or too tight and you make sure to not kegel will you have a very low risk of injury?

Thanks in advance!
