Preston's Mum is very protective (as are all Mum's) and not knowing anything about Football, demanded he had Finger Saves in his Gloves. We bought some and Preston did not like them and actually thought they hinded his grip. I took them out and until his Mum reads this post she still thinks he wears the Finger Saves.
A few Glove providers do not recommend them. They can be useful when a keeper is injured and needs extra support, but it’s always better not to rely on them. Without finger saves, the fingers and muscles can strengthen naturally, rather than depending on the spines for support.
So basically some keepers may need them to aid recovery but shouldn't rely on them
Who uses them?
