Hi, I have a full set of nearly new sports medicine boots, including overreach boots. Very good sort as they cover all vulnerable areas and are easily adjustable.
I wouldnt use sports boots as they offer no protection against strike injuries and get heavy in water. The Trizone all sport boots are worth a look, very good value and well designed.
The XC boots are fab. They aren't harder as such, but have a stronger external structure, so they are still flexible but offer a lot of protection. They are very well designed boots
