I normally wear a 12 or 12.5. Since 13 is too big for me, and since they didn't offer half sizes, I ordered size 12 (was expecting a 12D). What I received was slightly longer than my 12.5 shoes, probably closer to 13. But it was narrower than a D, probably closer to a B width. So what I thought would be a 12D is actually a 13B. What's further strange, when I ordered it didn't say "Wide", and the box doesn't indicate anything about width. But on the Amazon order page, every size says it's wide. These are definitely not wide LOL, they're a bit on the narrow side. The Terra brand has a lot of different patented features. These are the 4 features for this shoe: -Jetstride cushioning (insole) -Terra firma flex (plastic toe instead of metal, lighter weight, but claims to be the same level of protection) -Kryptoe (lighter fabric). -And they have a no-slip feature on the sole I will say I'm unimpressed with the "jetstride" insole - even though it's comfy at first, it's thin, flimsy, and prone to peeling apart. I see another reviewer said it fell apart after a few weeks, and I don't doubt it. I would replace the insoles with something better. Also, these are not lighter weight than my previous steel tipped work shoes (shoes, not boots). I have a very similar pair of work shoes from a generic chinese brand, the fabric is thinner, they're not as good, though they do have a real steel toe. Anyway, just for a ballpark comparison, my old steel tip shoes weigh 18 oz each, and these weigh 21.6 ounces each, so the Terra are almost 20% heavier. The outer fabric (synthetic, not leather) is a rip stop material, and double layered so it's soft on the inside. But it's not a breathable shoe at all, only a little bit on venting on the tongue. They're fairly waterproof too, you can get into 2-3" of water, snow, etc, for a few minutes and it won't bleed through to your socks. The material is also easy to clean, rinse and/or scrub, it won't hurt the shoe. However, the current asking price for these is $123, which seems steep. I know they have more amenities than the comparable occupational shoes you'd find at the local value mart. But still, brands like Brahma or Herman Survivors are less than half the price (ranging from $30-60 for steel tip shoes). I have no doubt the Terra are more durable. Still, I'm a bit mixed on these.
