Don't know about River Road boots, but if price is an issue
consider a pair of these

I bought a pair for around $65 from a discount clothing store. Froogle.com should offer the best mail order pricing.

The direct price is decent too

Don't let the low price fool you. These are much tougher than a giant box store's $65 boot.

The innards aren't as plush and padded as a $200 boot, but they're good for a few miles a day of walking, as in working outdoors for a day. They are built to last. I use them for stone work, chain saw / tree work, landscaping and warm weather riding. If I f' up and drop something, I want something durable between my li'l size 13 tootsies and the peril at hand, er... foot.

These are good for hot weather
