I've been running for the last 4 years and have always bought the Mizuno Wave Rider range. They are a great all rounder running shoe. With every purchase I would make sure to buy a half size up, as that has always worked for me in this style of shoe. Without giving it much consideration I went running in these this morning, only to realise they were too big! Too late to send back and so I'm hoping someone might be interested here. I believe they RRP at £140. I bought these last week for £70 and looking to sell for £40.
