well I have the x-boot synthetics(200's or 400's, i forget)...I love them. They are my practice or bad weather boot, and they are great for that. They did give me blisters when i first wore them, but i just doubled up socks and they are fine now. I bet the k-leather boots have great touch, and mold to the foot better.They are pretty...and expensive for the k-leather ones, but I'd think they would be worth it.
good luck. you can't go wrong with umbro.
