For summery-type shoes I'm particularly fond of MOSHULU.

I have a couple of pairs of these:-

moshulu shoes, for mens and ladies footwear. :: moshulu online

but in pastel pink and blue - I think they were a season or two ago. Sadly the shop near my mum has closed, so am always on the lookout for a supplier. Next nearers I think is Webbs of Wychbold.

Probably dearer than crocs, but well built and very comfy indeed.

p.s. I have very little style at all! but we are talking comfy summer shoes.

I might investigate a pair of those TUKs though...
