Well, I discovered my La Crosse 18" rubbers have a crack in them this weekend. I decided to purchase the Le Chameau Traqueur boots. What caught my attention to this model (aside from the good price) was this:

"Ultra-durable field and extreme terrain rubber boot. Natural rubber upper with Kevlar® reinforcement technology to protect against abrasion from groundcover."

Seems like just the thing for someone who is hard on their boots like me. They also have a half zip located at the calf of the boot. At the price of $157 shipped from the UK, it seemed like a good deal. Time will tell...
