I bought a pair of these. I like the sole, grippy and not too thick. Comfortable to wear. But the socks make my feet sweat - they were really wet after racing for an hour. The material does not breathe enough, for my feat anyway .I use these boots I found on ebay called light training boots for sports. Very light, warm, flexible with a soft grippy sole. Perfect for me. And best of all cheap £9.99 UK pounds.
