Are they Jungle Boots - judging from the profile of the sole, they are?
AFAIK Wellco Jungle Boots are imported. You shouldnt expect too much from these, as they are relatively cheaply made, but three miles is too soon for almost any boot to fall apart.
Take them back. Even better - get a refund and buy a quality pair of boots. Cheapo boots will destroy your feet.
I bought a pair of US made Altama Jungle Boots years ago, quickly replaced the sole with a VIBRAM heavy duty sole in the same style as the original, but FAR better for use on tarmac. Theyve held up fine. Ive used the boots on hard surfaces every year for many years since I got them. They are amongst my favorite summer footwear.
Dont use the generic hard soled jungle boots for use on hard surfaces only. They are murder on your back.
There was a time when some soldiers used these hard soled boots for running on hard surfaces during training. Ask them, if they would go back and change that decision, if they could.
IIRC the same company which owns Wellco also bought Altama. My Altamas predates that buyout by many years.
As for quality versus cheap boots, I bought a pair of LOWA boots a couple of decades ago - the sole only delaminated a couple of months ago. I used the boots very hard but also took good care of them. No eyelet ever gave way and the boots (non-Goretex) held their waterproof capability just fine with proper care and waxing. They only ever gave up the waterproof spirit after using the boots when digging in water filled holes in a swamp for a week. Color me impressed.
Buy quality over 'carp.' You wont regret it.
