The only thing is that wellies with the sides cut out might be a tad less uglier than Crocs, but just as useless.
I guess this was said tongue in cheek, but joking aside, crocks are marvellous for gardening unless it's really muddy or desperately cold, for several reasons:
a) They are incredibly comfy, even if you have wide feet or joint problems.
b) You can leave them in the porch and not worry about them being affected by dampness.
c) If they get muddy you can hose them or just run them under the tap.
d) they are dead easy to just slip on and off and you can wear thick socks with them for Winter to keep warm.
Here ends my testament to the magnificent Crock (and, No I don't work for them!)
