Not used them in the wild yet!
However, as a bit of an fyi for anyone interested,I think they (endura) have altered the sizing so they aren’t made for garden gnomes anymore!
XL for my size 10 5/10 Freeriders is spot on. Snug but not ridiculous torture to fit and remove.
I have no doubt the mud will work up under the cover on the actual sole BUT that’s the naturr of the beast…. and the decent toe grip should be welcome over the slick surface of the 5/10s in the thick mud.
Ymmv.👍
Got them from Cycle Store and added an endura snood to get the price over £50 to get a fiver off. Couldn’t find any deals on the xl size. Loads of deals on the smaller sizes about though.
