I like the Merrell trail glove but after the TG 3 they started mucking about with it. The TG-4 is a different shoe and the TG-5 is total Cr*p!.
They redesigned the last and made it more rectangular and used glue which dissolves in water in their water running shoes, and others I suspect to cut costs. Everyone hates the new designs and says stick with the originals (which you can't find anymore) and the versions from 2016 back.
The TG-3 is about $99.99 but I got mine at Gandermountain in 2016 for $35 on sale, so they are really hiking up the price. Retailers are making $50-$70 a shoe on these I think. If they can sell it on sale for $35-$55, they're getting them in at $30 from the dealer. They weigh about 8.1 oz per shoe.
