Hello Mwccwi, I thought that one of my students had the lace-on type, however they turned out to be the type that were an integral part of the boot and not the add on type. I did a little googling and found a couple of the lace on/detachable types. If you google "Alpenco ALFB-101 metatarsal guard" you will find one example, another can be found by googling "Intersafe metatarsal guard". Just googling metatarsal guards or various combinations of this topic yielded a number of different choices in complete boot/metatarsal offerings, they did range in price from slightly under $100 dollars to over $300 dollars. If I do run into other examples I will try to send them your way. Best regards, Allan
