what's the verdict on something like Grenson's Kirk
Personally I hate the lasts used for a lot of the cheaper Grensons such as the Kirk. I've not actually tried them on in person but in the linked image they look too long and very inelegant, almost look like clown-shoes.
The RL pair look much better. Some of the Grenson Rose models are excellent too, such as the Radley which are my current favourite pair of shoes.
