UPDATE2: The seller and manufacturer promptly refunded my money for the purchase without asking for a refund. Posted a photo and batch number. I really appreciate the quick solution to my problem. UPDATE: It's been less than 2 months and a boot has developed a crack where the rubber flexes. Shoes are easy to use in the yard. I have asked the seller for a refund or replacement but I am already on ebay 12 days past the expiry date for a return from them. Excellent garden, yard and hiking shoes. No more wet feet in the morning when I let go of my chicks. The tread is a bit odd walking down a paved driveway, but it's easy to clean. Pleasant in August.
