Just received three pairs from expresstrainers.something or other about two weeks back. Called up my usual guy who said they are discontinued so off I went to google. £27 per pair plus a bit for postage, can't go wrong I feel. Two pairs in 10.5 and one in 11 for when it's really cold and I have to wear thicker socks.
So far i have taken one of them up to 19km (last sunday) along a beach side track, mix of concrete, sand and pebbles and no complaints. good few 4 to 5 mile runs and they are feeling as commfortable as my old pair, which will be going to the bin soon.
I'm on my second pair of tubes. And will be getting my third shortly. I find them great for the money, and use them for running everything up to half marathon (as I have never run further than that ...yet). I am lucky in that I can wear pretty much any neutral shoe so no particular brand loyalty. I'll wear whatever is cheapest when I need new shoes.
One problem i do have with them is that they squeak a bit in the wet......can be annoying if that sort of thing bothers you. Never had the tubes fil up with anything yet, though I would imagine they could if worn i the right (or wrong) conditions.
Apart from that they are great, for me anyway. They do wear a bit quickly on the inside just under the ankle, both pairs I have had have worn through to the padding there long before the shoe is ready for the bin.
For contrast, they feel less cushioned than my nike pegasus, a bit more like my adidas something or other trail runners. Not super plush under foot but not too hard either. Maybe a bit like asics cumulus in feel.
I like them anyway, and for the price they can't be beaten.
