Thanks to all for responses and insight on this.
@ Marty_JG, I purchased that tape from Amazon. I have to say it appears completely different from stuff I bought from chemist. It certainly seems more robust, so I will be keen to trial it out when opportunity arises.
@ Mal Grey. I would say that my boots feel comfortable and I certainly feel there is room for toe movement (so to speak). As I said before, it is more that my second toe is longer than big toe (not sure if I can say considerably longer or not) and it is mainly this toe that bears the brunt of my blister problems/issues. Thanks for feedback and insight though, all appreciated.
Hopefully the new tape purchased can alleviate some of my issues.
