Dave, I use egg beaters and I noticed my shoes were getting grooves in the soles where they press on the pedals so I bought some of the shoe shields
I've found the shoe shields themselves are now bending very slightly in to the grooves, maybe I should have repaired the soles with milliput first.
I think, in future, I will fit the shoe shields from new.
Vava, I've got Northwave Celsius and Lizzard shoes, they are both vegan as far as I can tell. I searched around on their website at the time I bought them and it wasn't easy to find the information. I think in the end I downloaded their catalogue and it was only the soles in some of their shoes that used leather.
