this be the second pair of these I buy in a medium . I have read about the problem people have be have with fit . my hand be typically a little smaller than a medium glove and these fit snug , a little tighter than most medium glove I buy . because I think they be suppose to be tight , this be probably about what I expect . I hope that help on size for you . the velcro do not always stay on , but I be not sure of a better way to bind they at the wrist . I be not even sure you need the wrist strap because the glove fit snugly and do not slip . be they the best around ? I do not know , I have the opportunity to try other brands\/styles on at the store and do not like the way they feel , but never use they in a pool . -lrb- I be not `` one of those guy '' , the store either do not have these or they be outrageously price . -rrb- anyhow , I buy they for my daughter think they would be handy for a river-tube trip and try they in the pool . they do not feel like they be do much until you be do swimming . then you arm feel sore , and if you take they off and swim it feel like you hand have shrink ... and you can not get power any more . in other word , what a great work-out ! I buy the second pair for myself I like they so much .
