Why not make your own? ^_^ http://barefootted.com/sandals.pdf

Not really true. I used to go through Walmart's $20 a pair a month walking. $60-$160 shoes I usually do 400 km running on them.

90+kg here.

They might last as long, but do they work the same? I have $5 socks that outlast my shoes, but socks aren't exactly a replacement for shoes, right? Water shoes and barefoot running shoes seem like two different types of foot covering.
