Review: Wonderful Work Boot - We shopped for weeks looking for workboots that are comfortable...I'm certainly glad we waited. These Caterpillar Diagnostic Steel-Toe boots are everything we were looking for: Waterproof Steel Toe Arch Support Thermal Insulation Padded Shaft Leather exterior No-Slip Sole The padded shaft is extremely comfortable and the insulation adds to the "cushy" feeling without causing feet to be hot. They lace quickly and look nice on. The only question is if they will hold up - but only time will tell that and we've only had them a week. (I'll update this comment later about that)- If you are looking for a good workboot, that really is comfortable on the foot, then this is an excellent choice. My husband is on the jobsite 8-10 hours a day, walking on all manner of surfaces. He's very hard on workboots and we've bought a lot of them over the years, some have been good, others have not. But he's so happy with these, when they wear out, we will buy another pair just like them.
Review: High quality - Comfortable and water-resistant boots, they live up to their description, highly recommended.

Comfortable and water-resistant boots, they live up to their description, highly recommended.

### ⭐⭐⭐⭐⭐ Excellent pair of steel toes I've owned.
*by J***5 on April 11, 2015*

I had a pair of timberland pro pit bosses in black with steel toe. Now with steel toe if your not used to wearing them, you will noticed they are heavy. But after a while you barely realize they weight anything, I had the last pair for almost three years in roof tops, inside all over construction sites, they fit ok like a regular pair of boots, I saw these caterpillar boots and they were a bit more but I figured they have a lot of great selling features i will give them a shot. I ride suspended scaffolds, and walk all over roof tops and constantly up and down , these boots have great traction on building facades , wet roof tops, comfortable with the stock soles, and best yet they look awesome, definitely worth they extra 30bucks over the pit bosses only wished I would of saw these first , I will buy these again after three years maybe i will upgrade to the next level of there is one in cat. Best buy for me.
